14 December 2018, Apache Lucene™ 7.6.0 available
The Lucene PMC is pleased to announce the release of Apache Lucene 7.6.0.
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/downloads.html Please read CHANGES.txt for a full list of new features and changes:
Lucene 7.6.0 Release Highlights:
Index sorting corruption due to numeric overflow has been fixed. Indices affected by this bug can be detected by running the CheckIndex command on a 7.6+ release distribution.
- Better tessellation processing of Polygons including graceful exceptions for detecting invalid shapes.
- Points codec now supports selective indexing; the ability to designate dimensions as as "data only" dimensions that do not affect construction of the index.
- New Simple WKT Shape Parser builds lucene geometries (polygons, lines, rectangles) from WKT format.
New LatLonShapeLineQuery queries indexed shapes with arbitrary lines.
Performance in PerFieldMergeState#FilterFieldInfos has been improved from O(N) to O(1) lookup time.
