Apache Lucene全文检索引擎工具包
Lucene是apache软件基金会4 jakarta项目组的一个子项目,是一个开放源代码的全文检索引擎工具包,即它不是一个完整的全文检索引擎,而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(英文与德文两种西方语言)。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。
Apache Lucene 6.4.2 发布了,值得关注的更新如下:
LUCENE-7698: CommonGramsQueryFilter was producing a disconnected token graph, messing up phrase queries when it was used during query parsing
(Ere Maijala via Mike McCandless)
LUCENE-7676: Fixed FilterCodecReader to override more super-class methods. Also added TestFilterCodecReader class.
(Christine Poerschke)
LUCENE-7717: The UnifiedHighlighter and PostingsHighlighter were not highlighting prefix queries with multi-byte characters. TermRangeQuery is affected too.
(Dmitry Malinin, David Smiley)
