Apache Lucene 6.1.0 发布，全文索引引擎工具包

   <p style="text-align: center;"><img alt="" src="https://simg.open-open.com/show/9afbb10c5bc05af28e2dee6c1009fc53.png" /></p>    <p>Lucene不是一个完整的全文索引应用，而是是一个用Java写的全文索引引擎工具包，它可以方便的嵌入到各种应用中实现针对应用的全文索引/检索功能。Lucene的作者：Lucene的贡献者Doug Cutting是一位资深全文索引/检索专家，曾经是V-Twin搜索引擎(Apple的Copland操作系统的成就之一)的主要开发者，后在Excite担任高级系统架构设计师，目前从事于一些INTERNET底层架构的研究。他贡献出的Lucene的目标是为各种中小型应用程序加入全文检索功能。</p>    <p style="text-align: center;"><img
