lucene 7.1 jar包及文档

Lucene Change Log For more information on past and future Lucene versions, please see: http://s.apache.org/luceneversions ======================= Lucene 7.1.0 ======================= Changes in Runtime Behavior * Resolving of external entities in queryparser/xml/CoreParser is disallowed by default. See SOLR-11477 for details. New Features * LUCENE-7970: Add a shape to Geo3D that consists of multiple planes that approximate a true circle, rather than an ellipse, for non-spherical planet models. (Karl Wright, Ignacio Vera) * LUCENE-7955: Add support for the concept of "nearest distance" to Geo3D's GeoPath abstraction, which is the distance along the path to the point that is closest to the provided point. (Karl Wright) * LUCENE-7906: Add spatial relationships between all currently-defined Geo shapes. (Ignacio Vera) * LUCENE-7955: Add support for zero-width paths. (Karl Wright) * LUCENE-7936: Add serialization and deserialization support to Geo3D. (Karl Wright, Ignacio Vera) * LUCENE-7942: Distance computations now have the ability to accurately aggregate distances, rather than just doing sums. (Karl Wright) * LUCENE-7934: Add a planet model interface. (Karl Wright) * LUCENE-7918: Revamp the API for composites so that it's generic and can be used for many kinds of shapes. (Ignacio Vera) * LUCENE-7621: Add CoveringQuery, a query whose required number of matching clauses can be defined per document. (Adrien Grand) * LUCENE-7927: Add LongValueFacetCounts, to compute facet counts for individual numeric values (Mike McCandless) * LUCENE-7940: Add BengaliAnalyzer. (Md. Abdulla-Al-Sun via Robert Muir) * LUCENE-7392: Add point based LatLonBoundingBox as new RangeField Type. (Nick Knize) * LUCENE-7951: Spatial-extras has much better Geo3d support by implementing Spatial4j abstractions: SpatialContextFactory, ShapeFactory, BinaryCodec, DistanceCalculator. (Ignacio Vera, David Smiley) * LUCENE-7973: Update dictionary version for Ukrainian analyzer to 3.9.0 (Andriy Rysin via Dawid Weiss) * LUCENE-7974: Add FloatPointNearestNeighbor, an N-dimensional FloatPoint K-nearest-neighbor search implementation. (Steve Rowe) * LUCENE-7975: Change the default taxonomy facets cache to a faster byte[] (UTF-8) based cache. (Mike McCandless) * LUCENE-7972: DirectoryTaxonomyReader, in Lucene's facet module, now implements Accountable, so you can more easily track how much heap it's using. (Mike McCandless) * LUCENE-7982: A new NormsFieldExistsQuery matches documents that have norms in a specified field (Colin Goodheart-Smithe via Mike McCandless) Optimizations * LUCENE-7905: Optimize how OrdinalMap (used by SortedSetDocValuesFacetCounts and others) builds its map (Robert Muir, Adrien Grand, Mike McCandless) * LUCENE-7655: Speed up geo-distance queries in case of dense single-valued fields when most documents match. (Maciej Zasada via Adrien Grand) * LUCENE-7897: IndexOrDocValuesQuery now requires the range cost to be more than 8x greater than the cost of the lead iterator in order to use doc values. (Murali Krishna P via Adrien Grand) * LUCENE-7925: Collapse duplicate SHOULD or MUST clauses by summing up their boosts. (Adrien Grand) * LUCENE-7939: MinShouldMatchSumScorer now leverages two-phase iteration in order to be faster when used in conjunctions. (Adrien Grand) * LUCENE-7827: AnalyzingInfixSuggester doesn't create "textgrams" when minPrefixChar=0 (Mikhail Khludnev) Bug Fixes * LUCENE-7967: The GeoDegeneratePoint isWithin() method needed allowance for numerical precision. (Karl Wright) * LUCENE-7965: GeoBBoxFactory was constructing the wrong shape at the poles if the longitude span was greater than 180 degrees. (Karl Wright) * LUCENE-7916: Prevent ArrayIndexOutOfBoundsException if ICUTokenizer is used with a different ICU JAR version than it is compiled against. Note, this is not recommended, lucene-analyzers-icu contains binary data structures specific to ICU/Unicode versions it is built against. (Chris Koenig, Robert Muir) * LUCENE-7891: Lucene's taxonomy facets now uses a non-buggy LRU cache by default. (Jan-Willem van den Broek via Mike McCandless) * LUCENE-7959: Improve NativeFSLockFactory's exception message if it cannot create write.lock for an empty index due to bad permissions/read-only filesystem/etc. (Erick Erickson, Shawn Heisey, Robert Muir) * LUCENE-7968: AnalyzingSuggester would sometimes order suggestions incorrectly, it did not properly break ties on the surface forms when both the weights and the analyzed forms were equal. (Robert Muir) * LUCENE-7957: ConjunctionScorer.getChildren was failing to return all child scorers (Adrien Grand, Mike McCandless) * SOLR-11477: Disallow resolving of external entities in queryparser/xml/CoreParser by default. (Michael Stepankin, Olga Barinova, Uwe Schindler, Christine Poerschke) Build * SOLR-11181: Switch order of maven artifact publishing procedure: deploy first instead of locally installing first, to workaround a double repository push of *-sources.jar and *-javadoc.jar files. (Lynn Monson via Steve Rowe) * LUCENE-6673: Maven build fails for target javadoc:jar. (Ramkumar Aiyengar, Daniel Collins via Steve Rowe) * LUCENE-7985: Upgrade forbiddenapis to 2.4.1. (Uwe Schindler) Other * LUCENE-7948, LUCENE-7937: Upgrade randomizedtesting to 2.5.3 (minor fixes in test filtering for IDEs). (Mike Sokolov, Dawid Weiss) * LUCENE-7933: LongBitSet now validates the numBits parameter (Won Jonghoon, Mike McCandless) * LUCENE-7978: Add some more documentation about setting up build environment. (Anton R. Yuste via Uwe Schindler) * LUCENE-7983: IndexWriter.IndexReaderWarmer is now a functional interface instead of an abstract class with a single method (Dawid Weiss) * LUCENE-5753: Update TLDs recognized by UAX29URLEmailTokenizer. (Steve Rowe) ======================= Lucene 7.0.1 ======================= Bug Fixes * LUCENE-7957: ConjunctionScorer.getChildren was failing to return all child scorers (Adrien Grand, Mike McCandless) ======================= Lucene 7.0.0 ======================= New Features * LUCENE-7703: SegmentInfos now record the major Lucene version at index creation time. (Adrien Grand) * LUCENE-7756: LeafReader.getMetaData now exposes the index created version as well as the oldest Lucene version that contributed to the segment. (Adrien Grand) * LUCENE-7854: The new TermFrequencyAttribute used during analysis with a custom token stream allows indexing custom term frequencies (Mike McCandless) * LUCENE-7866: Add a new DelimitedTermFrequencyTokenFilter that allows to mark tokens with a custom term frequency (LUCENE-7854). It parses a numeric value after a separator char ('|') at the end of each token and changes the term frequency to this value. (Uwe Schindler, Robert Muir, Mike McCandless) * LUCENE-7868: Multiple threads can now resolve deletes and doc values updates concurrently, giving sizable speedups in update-heavy indexing use cases (Simon Willnauer, Mike McCandless) * LUCENE-7823: Pure query based naive bayes classifier using BM25 scores (Tommaso Teofili) * LUCENE-7838: Knn classifier based on fuzzified term queries (Tommaso Teofili) * LUCENE-7855: Added advanced options of the Wikipedia tokenizer to its factory. (Juan Pedro via Adrien Grand) API Changes * LUCENE-2605: Classic QueryParser no longer splits on whitespace by default. Use setSplitOnWhitespace(true) to get the old behavior. (Steve Rowe) * LUCENE-7369: Similarity.coord and BooleanQuery.disableCoord are removed. (Adrien Grand) * LUCENE-7368: Removed query normalization. (Adrien Grand) * LUCENE-7355: AnalyzingQueryParser has been removed as its functionality has been folded into the classic QueryParser. (Adrien Grand) * LUCENE-7407: Doc values APIs have been switched from random access to iterators, enabling future codec compression improvemen
