Apache Lucene 6.1.0 發布，全文索引引擎工具包

jopen 8年前發布 | 24K 次閱讀 Java 全文索引 Apache Lucene

Lucene不是一個完整的全文索引應用，而是是一個用Java寫的全文索引引擎工具包，它可以方便的嵌入到各種應用中實現針對應用的全文索引/檢索功能。Lucene的作者：Lucene的貢獻者Doug Cutting是一位資深全文索引/檢索專家，曾經是V-Twin搜索引擎(Apple的Copland操作系統的成就之一)的主要開發者，后在Excite擔任高級系統架構設計師，目前從事于一些INTERNET底層架構的研究。他貢獻出的Lucene的目標是為各種中小型應用程序加入全文檢索功能。
