-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 The Lucene PMC is pleased to announce the release of Apache Lucene 9.10.
Apache Lucene is a high-performance, full-featured search engine library written entirely in Java. It is a technology suitable for nearly any application that requires structured search, full-text search, faceting, nearest-neighbor search on high-dimensionality vectors, spell correction or query suggestions. This release contains numerous features, optimizations, and improvements, some of which are highlighted below. The release is available for immediate download at: https://lucene.apache.org/core/downloads.html Lucene 9.10 Release Highlights New Features * Support for similarity-based vector searches, ie. finding all nearest neighbors whose similarity is greater than a configured threshold from a query vector. See [Byte|Float]VectorSimilarityQuery. * Index sorting is now compatible with block joins. See IndexWriterConfig#setParentField. * MMapDirectory now takes advantage of the now finalized JDK foreign memory API internally when running on Java 22 (or later). This was only supported with Java 19 to 21 until now. * SIMD vectorization now takes advantage of JDK vector incubator on Java 22. This was only supported with Java 20 or 21 until now. Optimizations * Tail postings are now encoded using group-varint. This yielded speedups on queries that match lots of terms that have short postings lists in Lucene's nightly benchmarks. * Range queries on points now exit earlier when evaluating a segment that has no matches. This will improve performance when intersected with other queries that have a high up-front cost such as multi-term queries. * BooleanQueries that mix SHOULD and FILTER clauses now propagate minimum competitive scores to the SHOULD clauses, yielding significant speedups for top-k queries sorted by descending score. * IndexSearcher#count has been optimized on pure disjunctions of two term queries. ... plus a multitude of helpful bug fixes! Further details of changes are available in the change log available at: http://lucene.apache.org/core/9_10_0/changes/Changes.html. Please report any feedback to the mailing lists (http://lucene.apache.org/core/discussion.html) Note: The Apache Software Foundation uses an extensive mirroring network for distributing releases. It is possible that the mirror you are using may not have replicated the release yet. If that is the case, please try another mirror. This also applies to Maven access. -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEE5uIf/NzqFMlZEOplBRoPr3a8ZQcFAmXU4mEACgkQBRoPr3a8 ZQc1ig/9F0q3OeRjbkAuKXC0q+YxKBNfpXSC6bQin+40Jy+9rg/5QGbcIz4vOmXl TDN1gPhiQxG4DPUpCDbG6PpifJUBMfABiS0AlCFMocXOEvaPuXHXsHUIy6qmDNi/ 13FTsSx5JkI2egTkfYWDn4vpJzWamitn0u1anceDa3hcPHWqC8/6XiYlggaOe3BB z2L5s/zSM/Dhmgg6AWyA7jToVvkhWTs14qX9zkNMaMuJSJrY6K7c2HMORWDL19kU 8q+uAj/EqIeP5HK7w+fDY2TsFCBJC7LbgDu7a0mzZHFXaKLGE8xp7R5haHRzwUxk AabNKQMhVyfKEArxsHjMcY9kyvvEhU6AX/BRPnFDjLufyd0bUEq8gJOgx47qW61Q XSY+9jp/xNXKz9NuwoGP3zILt4Qi1Wqgw4VqBod2K8WbSuDjjjFzy18vyPAu7LYb iWaq/hQt4bwiO3gLhzZRzugQ7dMXBlXs6k7uYzXDPxqPREn11KqFv6zOCS1OfoCv xkU7ZxMGh4YUZzPuz7l1Ju4jwl2xHcNjj4BQMGPkwqnBMXUhBbq4l5zT5fVrBU9f IDFEBrUdvx98lAl61Rrftg7VSC1D3AYenHkj9+6FJ5J5d8iCMMQJVHc9DrMpe8g4 kZOFxOQchAL4OMGy8UsCafmphtSnIvWsqCYcpGcjl96DnoP2rq8= =uduX -----END PGP SIGNATURE-----
