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.
