Apache Lucene 7.5.0 已发布。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。 

Bug Fixes

  • IndexWriter#deleteDocs(Query... query) applies deletes to wrong documents if the index is sorted.

Changes in Runtime behavior

  • TieredMergePolicy now respects maxSegmentSizeMB by default when executing findForcedMerges and findForcedDeletesMerges.

Improvements

  • A new points based Shape Indexing and Searching that decomposes shapes into a triangular mesh and indexes individual triangles as a 6 dimension point.

  • A new ByteBuffer based Directory implementation that aims to replace the deprecated RAMDirectory.

  • The UnifiedHighlighter can now use the MatchesIterator API to highlight any query more accurately.

  • TopFieldComparator can now stop comparing documents if the index is sorted, even if hits still need to be visited to compute the hit count.

  • TieredMergePolicy can control how aggressively deletes should be reclaimed with the new deletesPctAllowed setting.
