Apache-2.0
* Wed Feb 21 2024 Gus Kenion <gus.kenion@suse.com>
- Use %patch -P N instead of deprecated %patchN.
* Tue Sep 19 2023 Fridrich Strba <fstrba@suse.com>
- Upgrade to version 8.11.2
* API Changes
+ LUCENE-9265: SimpleFSDirectory is deprecated in favor of
NIOFSDirectory.
+ LUCENE-9304: Removed ability to set
DocumentsWriterPerThreadPool on IndexWriterConfig.
The DocumentsWriterPerThreadPool is a packaged protected final
class which made it impossible to customize.
+ LUCENE-9339: MergeScheduler#merge doesn't accept a parameter
if a new merge was found anymore.
+ LUCENE-9330: SortFields are now responsible for writing
themselves into index headers if they are used as index sorts.
+ LUCENE-9340: Deprecate SimpleBindings#add(SortField).
+ LUCENE-9345: MergeScheduler is now decoupled from IndexWriter.
Instead it accepts a MergeSource interface that offers the
basic methods to acquire pending merges, run the merge and do
accounting around it.
+ LUCENE-9349: QueryVisitor.consumeTermsMatching() now takes a
Supplier<ByteRunAutomaton> to enable queries that build large
automata to provide them lazily. TermsInSetQuery switches to
using this method to report matching terms.
+ LUCENE-9366: DocValues.emptySortedNumeric() no longer takes a
maxDoc parameter
+ LUCENE-7822: CodecUtil#checkFooter(IndexInput, Throwable) now
throws a CorruptIndexException if checksums mismatch or if
checksums can't be verified.
+ LUCENE-7020: TieredMergePolicy#setMaxMergeAtOnceExplicit is
deprecated and the number of segments that get merged via
explicit merges is unlimited by default.
+ LUCENE-9437: Lucene's facet module's
DocValuesOrdinalsReader.decode method is now public, making it
easier for applications to decode facet ordinals into their
corresponding labels
+ LUCENE-9449: Field comparators for numeric fields and _doc
were moved to their own package. TopFieldCollector sets
TotalHits.relation to GREATER_THAN_OR_EQUAL_TO, as soon as the
requested total hits threshold is reached, even though in some
cases no skipping optimization is applied and all hits are
collected.
+ LUCENE-9515: IndexingChain now accepts individual primitives
rather than a DocumentsWriterPerThread instance in order to
create a new DocConsumer.
+ LUCENE-9680: Removed deprecation warning from
IndexWriter#getFieldNames().
+ LUCENE-9902: Change the getValue method from IntTaxonomyFacets
to be protected instead of private. Users can now access the
count of an ordinal directly without constructing an extra
FacetLabel. Also use variable length arguments for the
getOrdinal call in TaxonomyReader.
+ LUCENE-9962: DrillSideways allows sub-classes to provide
"drill down" FacetsCollectors. They may provide a null
collector if they choose to bypass "drill down" facet
collection.
+ LUCENE-10027: Add a new Directory reader open API from
indexCommit and a custom comparator for sorting leaf readers
+ LUCENE-10036: Replaced the ScoreCachingWrappingScorer ctor
with a static factory method that ensures unnecessary wrapping
doesn't occur.
* New Features
+ LUCENE-7889: Grouping by range based on values from
DoubleValuesSource and LongValuesSource
+ LUCENE-8962: Add IndexWriter merge-on-commit feature to
selectively merge small segments on commit, subject to a
configurable timeout, to improve search performance by
reducing the number of small segments for searching
+ LUCENE-8962: Add IndexWriter merge-on-refresh feature to
selectively merge small segments on getReader, subject to a
configurable timeout, to improve search performance by
reducing the number of small segments for searching.
+ LUCENE-9378: Doc values now allow configuring how to trade
compression for retrieval speed.
+ LUCENE-9385: Add FacetsConfig option to control which
drill-down terms are indexed for a FacetLabel
+ LUCENE-9386: RegExpQuery added case insensitive matching
option.
+ LUCENE-9413: Add CJKWidthCharFilter and its factory
+ LUCENE-9444: Add utility class to retrieve facet labels from
the taxonomy index for a facet field so such fields do not
also have to be redundantly stored
+ LUCENE-9484: Allow sorting an index after it was created.
With SortingCodecReader, existing unsorted segments can be
wrapped and merged into a fresh index using
IndexWriter#addIndices API.
+ LUCENE-9507: Custom order for leaves in IndexReader and
IndexWriter
+ LUCENE-9537: Added smoothingScore method and default
implementation to Scorable abstract class. The smoothing score
allows scorers to calculate a score for a document where the
search term or subquery is not present. The smoothing score
acts like an idf so that documents that do not have terms or
subqueries that are more frequent in the index are not
penalized as much as documents that do not have less frequent
terms or subqueries and prevents scores which are the product
or terms or subqueries from going to zero. Added the
implementation of the Indri AND and the
IndriDirichletSimilarity from the academic Indri search
engine: http://www.lemurproject.org/indri.php.
+ LUCENE-9552: New LatLonPoint query that accepts an array of
LatLonGeometries.
+ LUCENE-9553: New XYPoint query that accepts an array of
XYGeometries.
+ LUCENE-9572: TypeAsSynonymFilter has been enhanced support
ignoring some types, and to allow the generated synonyms to
copy some or all flags from the original token
+ LUCENE-9574 A token filter to drop tokens that match all
specified flags.
+ LUCENE-9575: PatternTypingFilter has been added to allow
setting a type attribute on tokens based on a configured set
of regular expressions
+ LUCENE-9594: FeatureField supports newLinearQuery that for
scoring uses raw indexed values of features without any
transformation.
+ LUCENE-9641: LatLonPoint query support for spatial
relationships.
+ LUCENE-9694: New tool for creating a deterministic index to
enable benchmarking changes on a consistent multi-segment
index even when they require re-indexing.
+ LUCENE-9950: New facet counting implementation for general
string doc value fields (SortedSetDocValues / SortedDocValues)
not created through FacetsConfig
+ LUCENE-10035: The SimpleText codec now writes skip lists.
+ LUCENE-10083: Analyzer and stemmer for Telugu language
* Improvements
+ LUCENE-9276: Use same code-path for updateDocuments and
updateDocument in IndexWriter and DocumentsWriter.
+ LUCENE-9279: Update dictionary version for Ukrainian analyzer
to 4.9.1
+ LUCENE-8050: PerFieldDocValuesFormat should not get the
DocValuesFormat on a field that has no doc values.
+ LUCENE-9304: Removed ThreadState abstraction from
DocumentsWriter which allows pooling of DWPT directly and
improves the approachability of the IndexWriter code.
+ LUCENE-9324: Add an ID to SegmentCommitInfo in order to
compare commits for equality and make snapshots incremental on
generational files.
+ LUCENE-9342: TotalHits' relation will be EQUAL_TO when the
number of hits is lower than TopDocsColector's numHits
+ LUCENE-9353: Metadata of the terms dictionary moved to its own
file, with the '.tmd' extension. This allows checksums of
metadata to be verified when opening indices and helps save
seeks when opening an index.
+ LUCENE-9359: SegmentInfos#readCommit now always returns a
CorruptIndexException if the content of the file is invalid.
+ LUCENE-9393: Make FunctionScoreQuery use ScoreMode.COMPLETE
for creating the inner query weight when ScoreMode.TOP_DOCS
is requested.
+ LUCENE-9392: Make FacetsConfig.DELIM_CHAR publicly accessible
+ LUCENE-9397: UniformSplit supports encodable fields metadata.
+ LUCENE-9396: Improved truncation detection for points.
+ LUCENE-9402: Let MultiCollector handle minCompetitiveScore
+ LUCENE-8574: Add a new ExpressionValueSource which will
enforce only one value per name per hit in dependencies,
ExpressionFunctionValues will no longer recompute already
computed values
+ LUCENE-9416: Fix CheckIndex to print an invalid non-zero norm
as unsigned long when detecting corruption.
+ LUCENE-9440: FieldInfo#checkConsistency called twice from
Lucene50(60)FieldInfosFormat#read; Removed the (redundant?)
assert and do these checks for real.
+ LUCENE-9446: In BooleanQuery rewrite, always remove
MatchAllDocsQuery filter clauses when possible.
+ LUCENE-9501: Improve coverage for Asserting* test classes:
make sure to handle singleton doc values, and sometimes
exercise Weight#scorer instead of Weight#bulkScorer for
top-level queries.
+ LUCENE-9511: Include StoredFieldsWriter in DWPT accounting
to ensure that it's heap consumption is taken into account
when IndexWriter stalls or should flush DWPTs.
+ LUCENE-9514: Include TermVectorsWriter in DWPT accounting to
ensure that it's heap consumption is taken into account when
IndexWriter stalls or should flush DWPTs.
+ LUCENE-9523: In query shapes over shape fields, skip points
while traversing the BKD tree when the relationship with the
document is already known.
+ LUCENE-9539: Use more compact datastructures to represent
sorted doc-values in memory when sorting a segment before
flush and in SortingCodecReader.
+ LUCENE-9458: WordDelimiterGraphFilter should order tokens at
the same position by endOffset to emit longer tokens first.
The same graph is produced.
+ LUCENE-5309: Optimize facet counting for single-valued
SSDV / StringValueFacetCounts.
+ LUCENE-9023: GlobalOrdinalsWithScore should not compute
occurrences when the provided min is 1.
+ LUCENE-9177: ICUNormalizer2CharFilter no longer requires
normalization-inert characters as boundaries for incremental
processing, vastly improving worst-case performance.
+ LUCENE-9455: ExitableTermsEnum should sample timeout and
interruption check before calling next().
+ LUCENE-9662: Make CheckIndex concurrent by parallelizing
index check across segments.
+ LUCENE-9663: Add compression to terms dict from
SortedSet/Sorted DocValues.
+ LUCENE-9675: Binary doc values fields now expose their
configured compression mode in the attributes of the field
info.
+ LUCENE-9725: BM25FQuery was extended to handle similarities
beyond BM25Similarity. It was renamed to CombinedFieldQuery to
reflect its more general scope.
+ LUCENE-9877: Reduce index size by increasing allowable
exceptions in PForUtil from 3 to 7.
+ LUCENE-9687: Hunspell support improvements: add API for
spell-checking and suggestions, support compound words, fix
various behavior differences between Java and C++
implementations, improve performance
+ LUCENE-9917: The BEST_SPEED compression mode now trades more
compression ratio in exchange of faster reads.
+ LUCENE-9935: Enable bulk merge for stored fields with index sort.
+ LUCENE-9944: Allow DrillSideways users to provide their own
CollectorManager without also requiring them to provide an
ExecutorService.
+ LUCENE-9945: Extend DrillSideways to support exposing
FacetCollectors directly.
+ LUCENE-9946: Support for multi-value fields in
LongRangeFacetCounts and DoubleRangeFacetCounts.
+ LUCENE-9965: Added QueryProfilerIndexSearcher and
ProfilerCollector to support debugging query execution
strategy and timing.
+ LUCENE-9981: Operations.getCommonSuffix/Prefix(Automaton) is
now much more efficient, from a worst case exponential down to
quadratic cost in the number of states + transitions in the
Automaton. These methods no longer use the costly determinize
method, removing the risk of TooComplexToDeterminizeException
+ LUCENE-9981: Operations.determinize now throws
TooComplexToDeterminizeException based on too much "effort"
spent determinizing rather than a precise state count on the
resulting returned automaton, to better handle adversarial
cases like det(rev(regexp("(.*a){2000}"))) that spend lots of
effort but result in smallish eventual returned automata.
+ LUCENE-9983: Stop sorting determinize powersets unnecessarily.
+ LUCENE-10030: Lazily evaluate score in
DrillSidewaysScorer.doQueryFirstScoring
+ LUCENE-10043: Decrease default for LRUQueryCache's
skipCacheFactor to 10. This prevents caching a query clause
when it is much more expensive than running the top-level
query.
+ LUCENE-10103: Make QueryCache respect Accountable queries
* Optimizations
+ LUCENE-9254: UniformSplit keeps FST off-heap.
+ LUCENE-8103: DoubleValuesSource and QueryValueSource now use a
TwoPhaseIterator if one is provided by the Query.
+ LUCENE-9287: UsageTrackingQueryCachingPolicy no longer caches
DocValuesFieldExistsQuery.
+ LUCENE-9286: FST.Arc.BitTable reads directly FST bytes. Arc is
lightweight again and FSTEnum traversal faster.
+ LUCENE-7788: fail precommit on unparameterised log messages
and examine for wasted work/objects
+ LUCENE-9273: Speed up geometry queries by specialising
Component2D spatial operations. Instead of using a generic
relate method for all relations, we use specialize methods for
each one. In addition, the type of triangle is computed at
deserialization time, therefore we can be more selective when
decoding points of a triangle.
+ LUCENE-9087: Build always trees with full leaves and lower the
default value for maxPointsPerLeafNode to 512.
+ LUCENE-9148: Points now write their index in a separate file.
+ LUCENE-9280: Add an ability for field comparators to skip
non-competitive documents. Creating a TopFieldCollector with
totalHitsThreshold less than Integer.MAX_VALUE instructs
Lucene to skip non-competitive documents whenever possible.
For numeric sort fields the skipping functionality works when
the same field is indexed both with doc values and points.
To indicate that the same data is stored in these points and
doc values SortField#setCanUsePoints method should be used.
+ LUCENE-9395: ConstantValuesSource now shares a single
DoubleValues instance across all segments
+ LUCENE-9447, LUCENE-9486: Stored fields now get higer
compression ratios on highly compressible data.
+ LUCENE-9373: FunctionMatchQuery now accepts a "matchCost"
optimization hint.
+ LUCENE-9510: Indexing with an index sort is now faster by not
compressing temporary representations of the data.
+ LUCENE-9449: Enhance DocComparator to provide an iterator over
competitive documents when searching with "after". This
iterator can quickly position on the desired "after" document
skipping all documents and segments before "after".
+ LUCENE-9021: QueryParser: re-use the LookaheadSuccess
exception.
+ LUCENE-9346: WANDScorer now supports queries that have a
'minimumNumberShouldMatch' configured.
+ LUCENE-9536: Reduced memory usage for OrdinalMap when a
segment has all values.
+ LUCENE-9636: Faster decoding of postings for some numbers of
bits per value.
+ LUCENE-9673: Substantially improve RAM efficiency of how
MemoryIndex stores postings in memory, and reduced a bit of
RAM overhead in IndexWriter's internal postings book-keeping
+ LUCENE-9827: Speed up merging of stored fields and term
vectors for smaller segments.
+ LUCENE-9932: Performance improvement for BKD index building
+ LUCENE-9996: Improved memory efficiency of IndexWriter's RAM
buffer, in particular in the case of many fields and many
indexing threads.
+ LUCENE-10014: Lucene90DocValuesFormat was using too many bits
per value when compressing via gcd, unnecessarily wasting
index storage.
+ LUCENE-10022: Rewrite empty DisjunctionMaxQuery to
MatchNoDocsQuery.
+ LUCENE-10031: Slightly faster segment merging for sorted
indices.
+ LUCENE-10196: Improve IntroSorter with 3-ways partitioning
+ LUCENE-10481: FacetsCollector will not request scores if it
does not use them
* Bug Fixes
+ LUCENE-9300: Fix corruption of the new gen field infos when
doc values updates are applied on a segment created externally
and added to the index with IndexWriter#addIndexes(Directory).
+ LUCENE-9350: Partial reversion of LUCENE-9068; holding
levenshtein automata on FuzzyQuery can end up blowing up query
caches which use query objects as cache keys, so building the
automata is now delayed to search time again.
+ LUCENE-9259: Fix wrong NGramFilterFactory argument name for
preserveOriginal option
+ LUCENE-8849: DocValuesRewriteMethod.visit wasn't visiting its
embedded query
+ LUCENE-9258: DocTermsIndexDocValues assumed it was operating
on a SortedDocValues (single valued) field when it could be
multi-valued used with a SortedSetSelector
+ LUCENE-9164: Ensure IW processes all internal events before it
closes itself on a rollback.
+ LUCENE-8908: Return default value from objectVal when doc
doesn't match the query in QueryValueSource
+ LUCENE-9133: Fix for potential NPE in TermFilteredPresearcher
for empty fields
+ LUCENE-9309: Wait for #addIndexes merges when aborting merges.
+ LUCENE-9337: Ensure CMS updates it's thread accounting
datastructures consistently. CMS today releases it's lock
after finishing a merge before it re-acquires it to update the
thread accounting datastructures. This causes threading issues
where concurrently finishing threads fail to pick up pending
merges causing potential thread starvation on forceMerge calls
+ LUCENE-9314: Single-document monitor runs were using the less
efficient MultiDocumentBatch implementation.
+ LUCENE-9362: Fix equality check in
ExpressionValueSource#rewrite. This fixes rewriting of inner
value sources.
+ LUCENE-9405: IndexWriter incorrectly calls closeMergeReaders
twice when the merged segment is 100% deleted.
+ LUCENE-9400: Tessellator might build illegal polygons when
several holes share the shame vertex.
+ LUCENE-9417: Tessellator might build illegal polygons when
several holes share are connected to the same vertex.
+ LUCENE-9418: Fix ordered intervals over interleaved terms
+ LUCENE-9443: The UnifiedHighlighter was closing the underlying
reader when there were multiple term-vector fields. This was a
regression in 8.6.0.
+ LUCENE-9478: Prevent DWPTDeleteQueue from referencing itself
and leaking memory. The queue passed an implicit this
reference to the next queue instance on flush which leaked
about 500byte of memory on each full flush, commit or
getReader call.
+ LUCENE-9427: Fix a regression where the unified highlighter
didn't produce highlights on fuzzy queries that correspond to
exact matches.
+ LUCENE-9467: Fix NRTCachingDirectory to use
Directory#fileLength to check if a file already exists instead
of opening an IndexInput on the file which might throw a
AccessDeniedException in some Directory implementations.
+ LUCENE-9501: Fix a bug in
IndexSortSortedNumericDocValuesRangeQuery where it could
violate the DocIdSetIterator contract.
+ LUCENE-9401: Include field in ComplexPhraseQuery's toString()
+ LUCENE-9578: Fix TermRangeQuery when there is no upper bound
and the lower bound is the empty string excluded. This would
previously match no strings at all while it should match all
non-empty strings.
+ LUCENE-9524: Fix NPE in SpanWeight#explain when no scoring is
required and SpanWeight has null Similarity.SimScorer.
+ LUCENE-9508: DocumentsWriter was only stalling threads for 1
second allowing documents to be indexed even the
DocumentsWriter wasn't able to keep up flushing. Unless IW
can't make progress due to an ill behaving DWPT this issue
was barely noticeable.
+ LUCENE-9581: Japanese tokenizer should discard the compound
token instead of disabling the decomposition of long tokens
when discardCompoundToken is activated.
+ LUCENE-9595: Make Component2D#withinPoint implementations
consistent with ShapeQuery logic.
+ LUCENE-9606: Wrap boolean queries generated by shape fields
with a Constant score query.
+ LUCENE-9617: Fix per-field memory leak in
IndexWriter.deleteAll(). Reset next available internal field
number to 0 on FieldInfos.clear(), to avoid wasting FieldInfo
references.
+ LUCENE-9635: BM25FQuery - Mask encoded norm long value in
array lookup.
+ LUCENE-9642: When encoding triangles in ShapeField, make sure
generated triangles are CCW by rotating triangle points before
checking triangle orientation.
+ LUCENE-9661: Fix deadlock in TermsEnum.EMPTY that occurs when
trying to initialize TermsEnum and BaseTermsEnum at the same
time
+ LUCENE-9744: NPE on a degenerate query in
MinimumShouldMatchIntervalsSource
$MinimumMatchesIterator.getSubMatches().
+ LUCENE-9762: DoubleValuesSource.fromQuery (also used by
FunctionScoreQuery.boostByQuery) could throw an exception when
the query implements TwoPhaseIterator and when the score is
requested repeatedly.
+ LUCENE-9791: BytesRefHash.equals/find is now thread safe,
fixing a Luwak/Monitor bug causing registered queries to
sometimes fail to match.
+ LUCENE-9870: Fix Circle2D intersectsLine t-value (distance)
range clamp
+ LUCENE-9887: Fixed parameter use in RadixSelector.
+ LUCENE-9953: LongValueFacetCounts should count each document
at most once when determining the total count for a dimension.
Prior to this fix, multi-value docs could contribute a > 1
count to the dimension count.
+ LUCENE-9958: Fixed performance regression for boolean queries
that configure a minimum number of matching clauses.
+ LUCENE-9963: FlattenGraphFilter is now more robust when
handling incoming holes in the input token graph
+ LUCENE-9964: Duplicate long values in a document field should
only be counted once when using SortedNumericDocValuesFields
+ LUCENE-9967: Do not throw NullPointerException while trying
to handle another exception in ReplicaNode.start
+ LUCENE-9988: Fix DrillSideways correctness bug introduced in
LUCENE-9944
+ LUCENE-9991: Fix edge case failure in
TestStringValueFacetCounts
+ LUCENE-9999: CombinedFieldQuery can fail with an exception
when document is missing some fields.
+ LUCENE-10008: Respect ignoreCase in CommonGramsFilterFactory
+ LUCENE-10020: DocComparator should not skip docs with the same
docID on multiple sorts with search after
+ LUCENE-10026: Fix CombinedFieldQuery equals and hashCode,
which ensures query rewrites don't drop CombinedFieldQuery
clauses.
+ LUCENE-10039: Correct CombinedFieldQuery scoring when there is
a single field.
+ LUCENE-10046: Counting bug fixed in StringValueFacetCounts.
+ LUCENE-10060: Ensure DrillSidewaysQuery instances never get
cached.
+ LUCENE-10070 Skip deleted docs when accumulating facet counts
for all docs
+ LUCENE-10081: KoreanTokenizer should check the max backtrace
gap on whitespaces.
+ LUCENE-10106: Sort optimization can wrongly skip the first
document of each segment
+ LUCENE-10110: MultiCollector now handles single leaf collector
that wants to skip low-scoring hits but the combined score
mode doesn't allow it
+ LUCENE-10111: Missing calculating the bytes used of
DocsWithFieldSet in NormValuesWriter
+ LUCENE-10116: Missing calculating the bytes used of
DocsWithFieldSet and currentValues in
SortedSetDocValuesWriter
+ LUCENE-10119: Sort optimization with search_after can wrongly
skip documents whose values are equal to the last value of the
previous page
+ LUCENE-10126: Sort optimization with a chunked bulk scorer can
wrongly skip documents
+ LUCENE-10134: ConcurrentSortedSetDocValuesFacetCounts
shouldn't share liveDocs Bits across threads
+ LUCENE-10154: NumericLeafComparator to define getPointValues
+ LUCENE-10208: Ensure that the minimum competitive score does
not decrease in concurrent search
+ LUCENE-10477: Highlighter:
WeightedSpanTermExtractor.extractWeightedSpanTerms to
Query#rewrite multiple times if necessary
+ LUCENE-10564: Make sure SparseFixedBitSet#or updates
ramBytesUsed
* Documentation
+ LUCENE-9424: Add a performance warning to
AttributeSource.captureState javadocs
* Changes in runtime behaviour
+ LUCENE-9539: SortingCodecReader now doesn't cache doc values
fields anymore. Previously, SortingCodecReader used to cache
all doc values fields after they were loaded into memory.
This reader should only be used to sort segments after the
fact using IndexWriter#addIndices.
* Other
+ LUCENE-9257: Always keep FST off-heap. FSTLoadMode, Reader
attributes and openedFromWriter removed.
+ LUCENE-9272: Checksums of the terms index are now verified
when LeafReader#checkIntegrity is called rather than when
opening the index.

builder generates the intermediate tree representation to be
equal to the one dimensional case to avoid unnecessary tree
and leaves rotation.
+ LUCENE-9288: poll_mirrors.py release script can handle HTTPS
mirrors.
+ LUCENE-9232: Fix or suppress 13 resource leak precommit
warnings in lucene/replicator

resilient for CONTAINS queries.
+ LUCENE-9512: Move LockFactory stress test to be a
unit/integration test.
+ LUCENE-9637: Removes some unused code and replaces the Point
implementation on ShapeField/ShapeQuery random tests.
+ LUCENE-9836: Removed the pure Maven build. It is no longer
possible to build artifacts using Maven (this feature was no
longer working correctly). Due to migration to Gradle for
Lucene/Solr 9.0, the maintenance of the Maven build was no
longer reasonable. POM files are generated for deployment to
Maven Central only. Please use "ant generate-maven-artifacts"
to produce and deploy artifacts to any repository.
+ LUCENE-9836: Migrate Maven tasks to use
"maven-resolver-ant-tasks" instead of the no longer maintained
"maven-ant-tasks".

+ LUCENE-9116: PostingsWriterBase and PostingsReaderBase no
longer support setting a field's metadata via a 'long[]'.
+ LUCENE-9116: The FSTOrd postings format has been removed.
+ LUCENE-8369: Remove obsolete spatial module.
+ LUCENE-8621: Refactor LatLonShape, XYShape, and all query and
utility classes to core.
+ LUCENE-9218: XY geometries API works in float space.
+ LUCENE-9212: Intervals.multiterm() takes CompiledAutomaton
rather than plain Automaton
+ LUCENE-9150: Restore support for dynamic PlanetModel in
spatial3d.
+ LUCENE-9171: QueryBuilder.newTermQuery() and
.newSynonymQuery() now take boost parameters.
+ LUCENE-9029: Deprecate SloppyMath toRadians/toDegrees in
favor of Java Math.
+ LUCENE-8620: Add CONTAINS support for LatLonShape and XYShape.
+ LUCENE-9050: MultiTermIntervalsSource.visit() was not calling
back to its visitor.
+ LUCENE-8909: IndexWriter#getFieldNames() method is used to
get fields present in index. After LUCENE-8316, this method is
no longer required. Hence, deprecate
IndexWriter#getFieldNames() method.
+ LUCENE-8755: SpatialPrefixTreeFactory now consumes the
"version" parsed with Lucene's Version class. The quad and
packed quad prefix trees are sensitive to this. It's
recommended to pass the version like you should do likewise
for analysis components for tokenized text, or else changes to
the encoding in future versions may be incompatible with older
indexes.
+ LUCENE-8956: QueryRescorer now only sorts the first topN hits
instead of all initial hits.
+ LUCENE-8921: IndexSearcher.termStatistics() no longer takes a
TermStates; it takes the docFreq and totalTermFreq. And don't
call if docFreq <= 0. The previous implementation survives as
deprecated and final. It's removed in 9.0.
+ LUCENE-8990: PointValues#estimateDocCount(visitor) estimates
the number of documents that would be matched by the given
IntersectVisitor. THe method is used to compute the cost() of
ScorerSuppliers instead of
PointValues#estimatePointCount(visitor).
+ LUCENE-8865: IndexSearcher now uses Executor instead of
ExecutorService. This change is fully backwards compatible
since ExecutorService directly implements Executor.
+ LUCENE-8856: Intervals queries have moved from the sandbox to
the queries module.
+ LUCENE-8893: Intervals.wildcard() and Intervals.prefix()
methods now take BytesRef rather than String.
+ LUCENE-3041: A query introspection API has been added.
Queries should implement a visit() method, taking a
QueryVisitor, and either pass the visitor down to any child
queries, or call a visitX() or consumeX() method on it. All
locations in the code that called Weight.extractTerms() have
been changed to use this API, and the extractTerms() method
has been deprecated.
+ LUCENE-8735: Directory.getPendingDeletions is now abstract to
ensure subclasses override it. FilterDirectory now delegates
the call, ensuring correct default behaviour for subclasses.
+ LUCENE-8662: TermsEnum.seekExact(BytesRef) to abstract and
delegate seekExact(BytesRef) in
FilterLeafReader.FilterTermsEnum.
+ LUCENE-8469: Deprecated StringHelper.compare has been removed.
+ LUCENE-8039: Introduce a "delta distance" method set to
GeoDistance. This allows distance calculations, especially for
paths, to take into account an "excursion" to include the
specified point.
+ LUCENE-8007: Index statistics Terms.getSumDocFreq(),
Terms.getDocCount() are now required to be stored by codecs.
Additionally, TermsEnum.totalTermFreq() and
Terms.getSumTotalTermFreq() are now required: if frequencies
are not stored they are equal to TermsEnum.docFreq() and
Terms.getSumDocFreq(), respectively, because all freq() values
equal 1.
+ LUCENE-8038: Deprecated PayloadScoreQuery constructors have
been removed
+ LUCENE-8014: Similarity.computeSlopFactor() and
Similarity.computePayloadFactor() have been removed
+ LUCENE-7996: Queries are now required to produce positive
scores.
+ LUCENE-8099: CustomScoreQuery, BoostedQuery and BoostingQuery
have been removed
+ LUCENE-8012: Explanation now takes Number rather than float
+ LUCENE-8116: SimScorer now only takes a frequency and a norm
as per-document scoring factors.
+ LUCENE-8113: TermContext has been renamed to TermStates, and
can now be constructed lazily if term statistics are not
required
+ LUCENE-8242: Deprecated method
IndexSearcher#createNormalizedWeight() has been removed
+ LUCENE-8267: Memory codecs removed from the codebase
(MemoryPostings, MemoryDocValues).
+ LUCENE-8144: Moved QueryCachingPolicy.ALWAYS_CACHE to the
test framework.
+ LUCENE-8356: StandardFilter and StandardFilterFactory have
been removed
+ LUCENE-8373: StandardAnalyzer.ENGLISH_STOP_WORD_SET has been
removed
+ LUCENE-8388: Unused PostingsEnum#attributes() method has been
removed
+ LUCENE-8405: TopDocs.maxScore is removed. IndexSearcher and
TopFieldCollector no longer have an option to compute the
maximum score when sorting by field.
+ LUCENE-8411: TopFieldCollector no longer takes a fillFields
option, it now always fills fields.
+ LUCENE-8412: TopFieldCollector no longer takes a
trackDocScores option. Scores need to be set on top hits via
TopFieldCollector#populateScores instead.
+ LUCENE-6228: A new Scorable abstract class has been added,
containing only those methods from Scorer that should be
called from Collectors. LeafCollector.setScorer() now takes a
Scorable rather than a Scorer.
+ LUCENE-8475: Deprecated constants have been removed from
RamUsageEstimator.
+ LUCENE-8483: Scorers may no longer take null as a Weight
+ LUCENE-8352: TokenStreamComponents is now final, and can take
a Consumer<Reader> in its constructor
+ LUCENE-8498: LowerCaseTokenizer has been removed, and
CharTokenizer no longer takes a normalizer function.
+ LUCENE-7875: Moved MultiFields static methods out of the
class. getLiveDocs is now in MultiBits which is now public.
getMergedFieldInfos and getIndexedFields are now in
FieldInfos. getTerms is now in MultiTerms.
getTermPositionsEnum and getTermDocsEnum were collapsed and
renamed to just getTermPostingsEnum and moved to MultiTerms.
+ LUCENE-8513: MultiFields.getFields is now removed. Please
avoid this class, and Fields in general, when possible.
+ LUCENE-8497: MultiTermAwareComponent has been removed, and in
its place TokenFilterFactory and CharFilterFactory now expose
type-safe normalize() methods. This decouples normalization
from tokenization entirely.
+ LUCENE-8597: IntervalIterator now exposes a gaps() method
that reports the number of gaps between its component
sub-intervals. This can be used in a new filter available via
Intervals.maxgaps().
+ LUCENE-8609: Remove IndexWriter#numDocs() and
IndexWriter#maxDoc() in favor of IndexWriter#getDocStats().
* Changes in Runtime Behavior
+ LUCENE-8671: Load FST off-heap also for ID-like fields if
reader is not opened from an IndexWriter.
+ LUCENE-8730: WordDelimiterGraphFilter always emits its
original token first. This brings its behaviour into line with
the deprecated WordDelimiterFilter, so that the only
difference in output between the two is in the position length
attribute.
+ LUCENE-7386: Disjunctions nested in disjunctions are now
flattened. This might trigger changes in the produced scores
due to changes to the order in which scores of sub clauses are
summed up.
+ LUCENE-8756: MoreLikeThisQuery now respects custom term
frequencies (TermFrequencyAttribute) at search time
+ LUCENE-8333: Switch MoreLikeThis.setMaxDocFreqPct to use
maxDoc instead of numDocs.
+ LUCENE-7837: Indices that were created before the previous
major version will now fail to open even if they have been
merged with the previous major version.
+ LUCENE-8020: Similarities are no longer passed terms that
don't exist by queries such as SpanOrQuery, so scoring
formulas no longer require divide-by-zero hacks.
IndexSearcher.termStatistics/collectionStatistics return null
instead of returning bogus values for a non-existent term or
field.
+ LUCENE-7996: FunctionQuery and FunctionScoreQuery now return
a score of 0 when the function produces a negative value.
+ LUCENE-8116: Similarities now score fields that omit norms as
if the norm was 1. This might change score values on fields
that omit norms.
+ LUCENE-8134: Index options are no longer automatically
downgraded.
+ LUCENE-8031: Length normalization correctly reflects omission
of term frequencies.
+ LUCENE-7444: StandardAnalyzer no longer defaults to removing
English stopwords
+ LUCENE-8060: IndexSearcher's search and searchAfter methods
now only compute total hit counts accurately up to 1,000 in
order to enable top-hits optimizations such as block-max WAND
(LUCENE-8135).
+ LUCENE-8505: IndexWriter#addIndices will now fail if the
target index is sorted but the candidate is not.
+ LUCENE-8535: Highlighter and FVH doesn't support ToParent and
ToChildBlockJoinQuery out of the box anymore. In order to
highlight on Block-Join Queries a custom
WeightedSpanTermExtractor / FieldQuery should be used.
+ LUCENE-8563: BM25 scores don't include the (k1+1) factor in
their numerator anymore. This doesn't affect ordering as this
is a constant factor which is the same for every document.
+ LUCENE-8509: WordDelimiterGraphFilter will no longer set the
offsets of internal tokens by default, preventing a number of
bugs when the filter is chained with tokenfilters that change
the length of their tokens
+ LUCENE-8633: IntervalQuery scores do not use term weighting
any more, the score is instead calculated as a function of the
sloppy frequency of the matching intervals.
+ LUCENE-8635: FSTs can now remain off-heap, accessed via
IndexInput, and the default codec's term dictionary
(BlockTreeTermsReader) will now leave the FST for the terms
index off-heap for non-primary-key fields using MMapDirectory,
reducing heap usage for such fields.
* New Features:
+ LUCENE-8903: Add LatLonShape and XYShape point query.
+ LUCENE-8707: Add LatLonShape and XYShape distance query.
+ LUCENE-9238: New XYPointField field and Queries for indexing,
searching and sorting cartesian points.
+ LUCENE-8936: Add SpanishMinimalStemFilter
+ LUCENE-8764 LUCENE-8945: Add "export all terms and doc freqs"
feature to Luke with delimiters.
+ LUCENE-8747: Composite Matches from multiple subqueries now
allow access to their submatches, and a new NamedMatches API
allows marking of subqueries and a simple way to find which
subqueries have matched on a given document
+ LUCENE-8769: Introduce Range Query For Multiple Connected
Ranges
+ LUCENE-8960: Introduce LatLonDocValuesPointInPolygonQuery for
LatLonDocValuesField
+ LUCENE-8753: New UniformSplitPostingsFormat (name
"UniformSplit") primarily benefiting in simplicity and
extensibility. New STUniformSplitPostingsFormat (name
"SharedTermsUniformSplit") that shares a single internal term
dictionary across fields.
+ LUCENE-8632: New XYShape Field and Queries for indexing and
searching general cartesian geometries.
+ LUCENE-8891: Snowball stemmer/analyzer for the Estonian
language.
+ LUCENE-8815: Provide a DoubleValues implementation for
retrieving the value of features without requiring a separate
numeric field. Note that as feature values are stored with
only 8 bits of mantissa the values returned may have a delta
from the original values indexed.
+ LUCENE-8803: Provide a FeatureSortfield to allow sorting
search hits by descending value of a feature. This is exposed
via the factory method FeatureField#newFeatureSort.
+ LUCENE-8784: The KoreanTokenizer now preserves punctuations
if discardPunctuation is set to false (defaults to true).
+ LUCENE-8812: Add new KoreanNumberFilter that can change
Hangul character to number and process decimal point. It is
similar to the JapaneseNumberFilter.
+ LUCENE-8362: Add doc-value support to range fields.
+ LUCENE-8766: Add monitor subproject (previously Luwak
monitoring library). This allows a stream of documents to be
matched against a set of registered queries in an efficien
manner, for use as a monitoring or classification tool.
+ LUCENE-7714: Add a numeric range query in sandbox that takes
advantage of index sorting.
+ LUCENE-8859: The completion suggester's postings format now
have an option to load its internal FST off-heap.
+ LUCENE-2562: The well-known graphical user interface for
inspecting Lucene indexes "Luke" was added as a Lucene module.
It can be started from the binary distribution by calling the
shell scripts in the module folder or from the source checkout
by using 'ant -f lucene/luke/build.xml run'. Luke provides a
Swing-based user interface and can be used to open Lucene or
Solr (or Elasticsearch) indexes, inspect documents, check
index commits and segments, or test (custom) analyzers. It
also has maintenance functions to check index structures and
force merge indexes for archival.
+ LUCENE-8340: LongPoint#newDistanceFeatureQuery may be used to
boost scores based on how close a value of a long field is
from a configurable origin. This is typically useful to boost
by recency.
+ LUCENE-8482: LatLonPoint#newDistanceFeatureQuery may be used
to boost scores based on the haversine distance of a
LatLonPoint field to a provided point. This is typically
useful to boost by distance.
+ LUCENE-8216: Added a new BM25FQuery in sandbox to blend
statistics across several fields using the BM25F formula.
+ LUCENE-8564: GraphTokenFilter is an abstract class useful for
token filters that need to read-ahead in the token stream and
take into account graph structures. This also changes
FixedShingleFilter to extend GraphTokenFilter
+ LUCENE-8612: Intervals.extend() treats an interval as if it
covered a wider span than it actually does, allowing users to
force minimum gaps between intervals in a phrase.
+ LUCENE-8629: New interval functions: Intervals.before(),
Intervals.after(), Intervals.within() and
Intervals.overlapping().
+ LUCENE-8622: Adds a minimum-should-match interval function
that produces intervals spanning a subset of a set of sources.
+ LUCENE-8645: Intervals.fixField() allows you to report
intervals from one field as if they came from another.
+ LUCENE-8646: New interval functions: Intervals.prefix() and
Intervals.wildcard()
+ LUCENE-8655: Add a getter in FunctionScoreQuery class in
order to access to the underlying DoubleValuesSource.
+ LUCENE-8697: GraphTokenStreamFiniteStrings correctly handles
side paths containing gaps
+ LUCENE-8702: Simplify intervals returned from vararg
Intervals factory methods
* Improvements:
+ LUCENE-9149: Increase data dimension limit in BKD.
+ LUCENE-9102: Add maxQueryLength option to DirectSpellchecker.
+ LUCENE-9091: UnifiedHighlighter HTML escaping should only
escape essentials
+ LUCENE-9105: UniformSplit postings format detects corrupted
index and better handles IO exceptions.
+ LUCENE-9106: UniformSplit postings format allows extension of
block/line serializers.
+ LUCENE-9093: UnifiedHighlighter's LengthGoalBreakIterator has
a new fragmentAlignment option to better center the first
match in the passage. Also the sizing point now pivots at the
center of the first match term and not its left edge. This
yields Passages that won't be identical to the previous
behavior.
+ LUCENE-9153: Allow WhitespaceAnalyzer to set a maxTokenLength
other than the default of 255
+ LUCENE-9152: Improve line intersections with polygons when
they are touching from the outside.
+ LUCENE-9123: Add new JapaneseTokenizer constructors with
discardCompoundToken option that controls whether the
tokenizer emits original (compound) tokens when the mode is
not NORMAL.
+ UCENE-9253: KoreanTokenizer now supports custom
dictionaries(system, unknown).
+ LUCENE-9171: QueryBuilder can now use BoostAttributes on
input token streams to selectively boost particular terms or
synonyms in parsed queries.
+ LUCENE-9002: Skip costly caching clause in LRUQueryCache if
it makes the query many times slower.
+ LUCENE-9006: WordDelimiterGraphFilter's catenateAll token is
now ordered before any token parts, like WDF did.
+ LUCENE-9028: introducing Intervals.multiterm()
+ LUCENE-9018: ConcatenateGraphFilter now has a configurable
separator.
+ LUCENE-9036: ExitableDirectoryReader may interupt scaning
over DocValues
+ LUCENE-9062: QueryVisitor now has a consumeTermsMatching()
method, allowing queries that match a class of terms to pass a
ByteRunAutomaton matching those that class back to the visitor.
+ LUCENE-9073: IntervalQuery to respond field on toString() and
explain()
+ LUCENE-8874: Show SPI names instead of class names in Luke
Analysis tab.
+ LUCENE-8894: Add APIs to find SPI names for
Tokenizer/CharFilter/TokenFilter factory classes.
+ LUCENE-8914: move the logic for discarding inner modes in
FloatPointNearestNeighbor to the IntersectVisitor so we take
advantage of the change introduced in LUCENE-7862.
+ LUCENE-8955: move the logic for discarding inner modes in
LatLonPoint NearestNeighbor to the IntersectVisitor so we take
advantage of the change introduced in LUCENE-7862.
+ LUCENE-8918: PhraseQuery throws exceptions at construction
time if it is passed null arguments.
+ LUCENE-8916: GraphTokenStreamFiniteStrings preserves all
Token attributes through its finite strings TokenStreams
+ LUCENE-8933: Check kuromoji user dictionary beforehand to
avoid unexpected runtime exceptions. (Tomoko Uchida
+ LUCENE-8906: Expose Lucene50PostingsFormat.IntBlockTermState
as public so that other postings formats can re-use it.
+ LUCENE-8942: Remove redundant parameters and improve
visibility strictness in LRUQueryCache
+ SOLR-13663: Introduce <SpanPositionRange> into XML Query
Parser
+ LUCENE-8952: Use a sort key instead of true distance in
NearestNeighbor
+ LUCENE-8620: Tessellator labels the edges of the generated
triangles whether they belong to the original polygon. This
information is added to the triangle encoding.
+ LUCENE-8964: Fix geojson shape parsing on string arrays in
properties
+ LUCENE-8976: Use exact distance between point and bounding
rectangle in FloatPointNearestNeighbor.
+ LUCENE-8966: The Korean analyzer now splits tokens on
boundaries between digits and alphabetic characters.
+ LUCENE-8984: MoreLikeThis MLT is biased for uncommon fields
+ LUCENE-7840: Non-scoring BooleanQuery now removes SHOULD
clauses before building the scorer supplier as opposed to
eliminating them during scoring construction.
+ LUCENE-8770: BlockMaxConjunctionScorer now leverages
two-phase iterators in order to avoid executing the second
phase when scorers don't intersect.
+ LUCENE-8781: FST lookup performance has been improved in many
cases by encoding Arcs using full-sized arrays with gaps. The
new encoding is enabled for postings in the default codec and
for suggesters.
+ LUCENE-8818: Fix smokeTestRelease.py encoding bug
+ LUCENE-8845: Allow Intervals.prefix() and
Intervals.wildcard() to specify their maximum allowed expansions
+ LUCENE-8875: Introduce a Collector optimized for use cases
when large number of hits are requested
+ LUCENE-8848 LUCENE-7757 LUCENE-8492: The UnifiedHighlighter
now detects that parts of the query are not understood by it,
and thus it should not make optimizations that result in no
highlights or slow highlighting. This generally works best for
WEIGHT_MATCHES mode. Consequently queries produced by
ComplexPhraseQueryParser and the surround QueryParser will now
highlight correctly.
+ LUCENE-8793: Luke enhanced UI for CustomAnalyzer: show
detailed analysis steps.
+ LUCENE-8855: Add Accountable to some Query implementations
+ LUCENE-8673: Use radix partitioning when merging dimensional
points instead of sorting all dimensions before hand.
+ LUCENE-8687: Optimise radix partitioning for points on heap.
+ LUCENE-8699: Change HeapPointWriter to use a single byte
array instead to a list of byte arrays. In addition a new
interface PointValue is added to abstract out the different
formats between offline and on-heap writers.
+ LUCENE-8703: Build point writers in the BKD tree only when
they are needed.
+ LUCENE-8652: SynonymQuery can now deboost the document
frequency of each term when blending the score of the synonym.
+ LUCENE-8631: The Korean's user dictionary now picks the
longest-matching word and discards the other matches.
+ LUCENE-8732: ConstantScoreQuery can now early terminate the
query if the minimum score is greater than the constant score
and total hits are not requested.
+ LUCENE-8750: Implements setMissingValue() on sort fields
produced from DoubleValuesSource and LongValuesSource
+ LUCENE-8701: ToParentBlockJoinQuery now creates a child
scorer that disallows skipping over non-competitive documents
if the score of a parent depends on the score of multiple
children (avg, max, min). Additionally the score mode 'none'
that assigns a constant score to each parent can early
terminate top scores's collection.
+ LUCENE-8751: Weight#matches now use the ScorerSupplier to
build scorers with a lead cost of 1 (single document).
+ LUCENE-8752: Japanese new era name '令和' (Reiwa) is added to
the dictionary used in JapaneseTokenizer so that the analyzer
handles the era name correctly. Reiwa is set to replace the
Heisei Era on May 1, 2019.
+ LUCENE-8671: Introduced reader attributes allows a per
IndexReader configuration of codec internals. This enables a
per reader configuration if FSTs are on- or off-heap on a per
field basis
+ LUCENE-8787: spatial-extras DateRangePrefixTree used to only
parse ISO-8601 timestamps with 0 or 3 digits of milliseconds
precision but now parses other lengths (although > 3 not
used).
+ LUCENE-7997: Add BaseSimilarityTestCase to sanity check
similarities. SimilarityBase switches to 64-bit doubles
internally to help avoid common numeric issues. Add missing
range checks for similarity parameters. Improve BM25 and
ClassicSimilarity's explanations.
+ LUCENE-8011: Improved similarity explanations.
+ LUCENE-4198: Codecs now have the ability to index score
impacts.
+ LUCENE-8135: Boolean queries now implement the block-max WAND
algorithm in order to speed up selection of top scored
documents.
+ LUCENE-8279: CheckIndex now cross-checks terms with norms.
+ LUCENE-8660: TopDocsCollectors now return an accurate count
(instead of a lower bound) if the total hit count is equal to
the provided threshold.
* Optimizations
+ LUCENE-9211: Add compression for Binary doc value fields.
+ LUCENE-4702: Better compression of terms dictionaries.
+ LUCENE-9228: Sort dvUpdates in the term order before applying
if they all update a single field to the same value. This
optimization can reduce the flush time by around 20% for the
docValues update user cases.
+ LUCENE-9245: Reduce AutomatonTermsEnum memory usage.
+ LUCENE-9237: Faster UniformSplit intersect TermsEnum.
+ LUCENE-9068: FuzzyQuery builds its Automaton up-front
+ LUCENE-9113: Faster merging of SORTED/SORTED_SET doc values.
+ LUCENE-9125: Optimize Automaton.step() with binary search and
introduce Automaton.next().
+ LUCENE-9147: The index of stored fields and term vectors in
now off-heap.
+ LUCENE-8928: When building a kd-tree for dimensions n > 2,
compute exact bounds for an inner node every N splits to
improve the quality of the tree. N is defined by
SPLITS_BEFORE_EXACT_BOUNDS which is set to 4.
+ BaseDirectoryReader no longer sums up the
'LeafReader#numDocs' of its leaves eagerly. This especially
helps when creating views of readers that hide documents,
since computing the number of live documents is an expensive
operation.
+ LUCENE-8992: TopFieldCollector and TopScoreDocCollector can
now share minimum scores across leaves concurrently.
+ LUCENE-8932: BKDReader's index is now stored off-heap when
the IndexInput is an instance of ByteBufferIndexInput.
+ LUCENE-9024: IntroSelector now falls back to the median of
medians algorithm instead of sorting when the maximum
recursion level is exceeded, providing better worst-case
runtime.
+ LUCENE-8920: The denser arcs of FST now index labels with a
bitset in order to provide near constant time access.
+ LUCENE-9027: Use SIMD instructions to decode postings.
+ LUCENE-9049: Remove FST cached root arcs now redundant with
labels indexed by bitset. This frees some on-heap FST space.
+ LUCENE-9045: Do not use TreeMap/TreeSet in BlockTree and
PerFieldPostingsFormat.
+ LUCENE-8922: DisjunctionMaxQuery more efficiently leverages
impacts to skip non-competitive hits.
+ LUCENE-8935: BooleanQuery with no scoring clause can now
early terminate the query when the total hits is not requested.
+ LUCENE-8941: Matches on wildcard queries will defer building
their full disjunction until a MatchesIterator is pulled
+ LUCENE-8755: spatial-extras quad and packed quad prefix trees
now index points faster.
+ LUCENE-8860: add additional leaf node level optimizations in
LatLonShapeBoundingBoxQuery.
+ LUCENE-8968: Improve performance of WITHIN and DISJOINT
queries for Shape queries by doing just one pass whenever
possible.
+ LUCENE-8939: Introduce shared count based early termination
across multiple slices
+ LUCENE-8980: Blocktree's seekExact now short-circuits false
if the term isn't in the min-max range of the segment. Large
perf gain for ID/time like data when populated sequentially.
+ LUCENE-8796: Use exponential search instead of binary search
in IntArrayDocIdSet#advance method
+ LUCENE-8865: Use incoming thread for execution if
IndexSearcher has an executor. Now caller threads execute at
least one search on an index even if there is an executor
provided to minimize thread context switching.
+ LUCENE-8868: New storing strategy for BKD tree leaves with
low cardinality. It stores the distinct values once with the
cardinality value reducing the storage cost.
+ LUCENE-8885: Optimise BKD reader by exploiting cardinality
information stored on leaves.
+ LUCENE-8896: Override default implementation of
IntersectVisitor#visit(DocIDSetBuilder, byte[]) for several queries.
+ LUCENE-8901: Load frequencies lazily only when needed in
BlockDocsEnum and BlockImpactsEverythingEnum
+ LUCENE-8888: Optimize distribution of points with data
dimensions in BKD tree leaves.
+ LUCENE-8311: Phrase queries now leverage impacts.
+ LUCENE-8040: Optimize IndexSearcher.collectionStatistics,
avoiding MultiFields/MultiTerms
+ LUCENE-4100: Disjunctions now support faster collection of
top hits when the total hit count is not required.
+ LUCENE-7993: Phrase queries are now faster if total hit
counts are not required.
+ LUCENE-8109: Boolean queries propagate information about the
minimum competitive score in order to make collection faster
if there are disjunctions or phrase queries as sub queries,
which know how to leverage this information to run faster.
+ LUCENE-8439: Disjunction max queries can skip blocks to
select the top documents if the total hit count is not required.
+ LUCENE-8204: Boolean queries with a mix of required and
optional clauses are now faster if the total hit count is not
required.
+ LUCENE-8448: Boolean queries now propagates the mininum score
to their sub-scorers.
+ LUCENE-8511: MultiFields.getIndexedFields is now optimized;
does not call getMergedFieldInfos
+ LUCENE-8507: TopFieldCollector can now update the minimum
competitive score if the primary sort is by relevancy and the
total hit count is not required.
+ LUCENE-8464: ConstantScoreScorer now implements
setMinCompetitveScore in order to early terminate the iterator
if the minimum score is greater than the constant score.
+ LUCENE-8607: MatchAllDocsQuery can shortcut when total hit
count is not required
+ LUCENE-8585: Index-time jump-tables for DocValues, for O(1)
advance when retrieving doc values.
* Bug Fixes
+ LUCENE-9084: Fix potential deadlock due to circular
synchronization in AnalyzingInfixSuggester
+ LUCENE-9115: NRTCachingDirectory no longer caches files of
unknown size.
+ LUCENE-9144: Fix error message on OneDimensionBKDWriter when
too many points are added to the writer.
+ LUCENE-9135: Make UniformSplit FieldMetadata counters long.
+ LUCENE-9200: Fix TieredMergePolicy to use double (not float)
math to make its merging decisions, fixing a corner-case bug
uncovered by fun randomized tests
+ LUCENE-9099: Unordered and Ordered interval queries now
correctly handle repeated subterms - ordered intervals could
supply an 'extra' minimized interval, resulting in odd
matches when combined with eg CONTAINS queries; and unordered
intervals would match duplicate subterms on the same position,
so an query for UNORDERED(foo, foo) would match a document
containing 'foo' only once.
+ LUCENE-9250: Add support for Circle2d#intersectsLine around
the dateline.
+ LUCENE-9243: Add fudge factor when creating a bounding box of
a XYCircle.
+ LUCENE-9239: Circle2D#WithinTriangle detects properly if a
triangle is Within distance.
+ LUCENE-9251: Fix bug in the polygon tessellator where edges
with different value on #isEdgeFromPolygon were bot filtered
out properly.
+ LUCENE-9263: Fix wrong transformation of distance in meters
to radians in Geo3DPoint.
+ LUCENE-9001: Fix race condition in SetOnce.
+ LUCENE-9030: Fix WordnetSynonymParser behaviour so it behaves
similar to SolrSynonymParser.
+ LUCENE-9054: Fix reproduceJenkinsFailures.py to not overwrite
junit XML files when retrying
+ LUCENE-9031: UnsupportedOperationException on
MatchesIterator.getQuery()
+ LUCENE-8996: maxScore was sometimes missing from distributed
grouped responses.
+ LUCENE-9055: Fix the detection of lines crossing triangles
through edge points.
+ LUCENE-9103: Disjunctions can miss some hits in some rare
conditions.
+ LUCENE-8755: spatial-extras quad and packed quad prefix trees
could throw a NullPointerException for certain cell edge
coordinates
+ LUCENE-9005: BooleanQuery.visit() would pull subVisitors from
its parent visitor, rather than from a visitor for its own
specific query. This could cause problems when BQ was nested
under another BQ. Instead, we now pull a MUST subvisitor, pass
it to any MUST subclauses, and then pull SHOULD, MUST_NOT and
FILTER visitors from it rather than from the parent.
+ LUCENE-8831: Fixed LatLonShapeBoundingBoxQuery .hashCode
methods.
+ LUCENE-8775: Improve tessellator to handle better cases where
a hole share a vertex with the polygon.
+ LUCENE-8785: Ensure new threadstates are locked before
retrieving the number of active threadstates. This causes
assertion errors and potentially broken field attributes in
the IndexWriter when IndexWriter#deleteAll is called while
actively indexing.
+ LUCENE-8804: Forbid calls to putAttribute on frozen FieldType
instances.
+ LUCENE-8828: Removes the buggy 'disallow overlaps' boolean
from Intervals.unordered(), and replaces it with a new
Intervals.unorderedNoOverlaps() method
+ LUCENE-8843: Don't ignore exceptions that are thrown when
trying to open a file in IOUtils#fsync.
+ LUCENE-8835: FileSwitchDirectory now respects the file
extension when listing directory contents to ensure we don't
expose pending deletes if both directory point to the same
underlying filesystem directory.
+ LUCENE-8853: FileSwitchDirectory now applies best effort to
place tmp files in the same directory as the target files.
+ LUCENE-8892: Add missing closing parentheses in
MultiBoolFunction's description()
+ LUCENE-8736: LatLonShapePolygonQuery returns incorrect WITHIN
results with shared boundaries. Point in Polygon now correctly
includes boundary points. Box and Polygon relations with
triangles have also been improved to correctly include
boundary points.
+ LUCENE-8712: Polygon2D does not detect crossings through
segment edges.
+ LUCENE-8720: NameIntCacheLRU (in the facets module) had an
int overflow bug that disabled cleaning of the cache
+ LUCENE-8726: ValueSource.asDoubleValuesSource() could leak a
reference to IndexSearcher
+ LUCENE-8719: FixedShingleFilter can miss shingles at the end
of a token stream if there are multiple paths with different
lengths.
+ LUCENE-8688: TieredMergePolicy#findForcedMerges now tries to
create the cheapest merges that allow the index to go down to
'maxSegmentCount' segments or less.
+ LUCENE-8477: Interval disjunctions could miss valid hits if
some of the clauses of the disjunction are minimized away. We
now rewrite intervals if a source contains a disjunction and
the internal gaps matter for matching. This behaviour can be
disabled if users are more interested in speed rather than
accuracy of matching.
+ LUCENE-8741: ValueSource.fromDoubleValuesSource() was casting
to Scorer instead of Scorable, leading to ClassCastExceptions
+ LUCENE-8754: Fix ConcurrentModificationException in
SegmentInfo if attributes are accessed in MergePolicy while
the merge is running
+ LUCENE-8765: Fixed validation of the number of added points
in KD trees.
