DATE, Apache Lucene™ 8.7 available

The Lucene PMC is pleased to announce the release of Apache Lucene 8.7.

Apache Lucene is a high-performance, full-featured text search engine library written entirely in Java. It is a technology suitable for nearly any application that requires full-text search, especially cross-platform.

This release contains numerous bug fixes, optimizations, and improvements, some of which are highlighted below. The release is available for immediate download at:

http://lucene.apache.org/core/mirrors-core-latest-redir.html

Lucene 8.7 Release Highlights:

  • Better compression of stored fields. Stored fields now use dictionaries in order to improve the compression ratio when there is a lot of redundancy across documents. This works for both the BEST_SPEED and the BEST_COMPRESSION modes.
  • Faster sorting by field. When a doc-value field is also indexed with points, Lucene now takes advantage of this points index in order to skip documents whose sort value is not competitive.
  • Faster flushing of stored fields when index sorting is enabled. This can significantly speed up indexing when a non-negligible amount of data is stored in the index and index sorting is enabled.

Further details of changes are available in the change log available at: http://lucene.apache.org/core/8_7/changes/Changes.html
