The Lucene PMC is pleased to announce the release of Apache Lucene 9.1.0.
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 9.1.0 Release Highlights
New features
- Lucene JARs are now proper Java modules, with module descriptors
and dependency information
- Support for filtering in nearest-neighbor vector search
- Support for intervals queries in the standard query syntax
- A new token filter SpanishPluralStemFilter for precise stemming of
Spanish plurals
Optimizations
- Up to 30% improvement in index throughput for high-dimensional vectors
- Up to 10% faster nearest neighbor searches on high-dimensional vectors
- Faster execution of "count" searches across different query types
- Faster counting for taxonomy facets
- Several other search speed-ups, including improvements to
PointRangeQuery, MultiRangeQuery, and CoveringRangeQuery
Other
- The test framework is now a module, so all classes have been moved
from to org.apache.lucene.tests.* to avoid package name conflicts
- Lucene now faithfully implements the HNSW algorithm for nearest
neighbor search by supporting multiple graph layers
… plus a number of helpful bug fixes!
Further details of changes are available in the change log available at:
http://lucene.apache.org/core/9_1_0/changes/Changes.html
and the migration guide available at:
https://lucene.apache.org/core/9_1_0/MIGRATE.html
Please report any feedback to the mailing lists
