[ANNOUNCE] Apache Lucene 10.1.0 released
The Lucene PMC is pleased to announce the release of Apache Lucene 10.1.0.
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 across high-dimensionality vectors, spell
correction or query suggestions.
This release contains numerous bug fixes, 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 10.1.0 Release Highlights:
#### New Features
* Add IndexInput::isLoaded to determine if the contents of an input is
resident in physical memory
* FeatureField now supports storing term vectors.
#### Improvements
* TieredMergePolicy now allows merging up to maxMergeAtOnce segments for
merges below the floor segment size, even if maxMergeAtOnce is greater than
segmentsPerTier. This makes it more efficient to configure
TieredMergePolicy to merge segments aggressively by configuring a high
value of floorSegmentSize (e.g. 64MB), a low value of segmentsPerTier (e.g.
4) and a high value of maxMergeAtOnce (e.g. 32).
#### Optimizations
* Many speedups to top-k query evaluation, in particular: top-level
disjunctions, filtered disjunctions, conjunctions, DisjunctionMaxQuery.
* Speedup to exhaustive evaluation of conjunctive queries by vectorizing
the intersection of postings lists.
* Reduced contention for top-k query evaluation when IndexSearcher is
configured with an executor.
... plus a multitude of helpful bug fixes!
