Apache Lucene 6.6.1 发布，Java 搜索引擎

Apache Lucene 6.6.1 发布了，Lucene 是 Apache 软件基金会的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。

更新内容：

1. LUCENE-7869: Changed MemoryIndex to sort 1d points. In case of 1d points, the PointInSetQuery.MergePointVisitor expects that these points are visited in ascending order. The memory index doesn’t do this and this can result in document with multiple points that should match to not match.

   (Martijn van Groningen)

2. LUCENE-7878: Fix query builder to keep the SHOULD clause that wraps multi-word synonyms.
