Apache Lucene 7.6.0 发布了，下载地址 >>> http://lucene.apache.org/core/downloads 。

Lucene 是 Apache 软件基金会一个开放源代码的全文检索引擎工具包，是一个全文检索引擎的架构，提供了完整的查询引擎和索引引擎，部分文本分析引擎。Lucene 的目的是为软件开发人员提供一个简单易用的工具包，以方便的在目标系统中实现全文检索的功能，或者是以此为基础建立起完整的全文检索引擎。

此版本包含许多错误修复、优化和改进，值得关注的如下：

Bug Fixes
   * 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.

Improvements
   * 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.
