Lucene 是 Apache 軟體基金會一個開放原始碼的全文檢索引擎工具包,是一個全文檢索引擎的架構,提供了完整的查詢引擎和索引引擎,部分文字分析引擎。Lucene 的目的是為軟體開發人員提供一個簡單易用的工具包,以方便的在目標系統中實現全文檢索的功能,或者是以此為基礎建立起完整的全文檢索引擎。
此版本包含許多錯誤修復、優化和改進,值得關注的如下:
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.
