Apache Solr 企业级全文搜索引擎
Solr是一个独立的企业级搜索应用服务器，它对外提供类似于Web-service的API接口。用户可以通过http请求，向搜索引擎服务器提交一定格式的XML文件，生成索引；也可以通过Http Get操作提出查找请求，并得到XML格式的返回结果；
Apache Solr 6.1.0 发布了。
一些改进提升：
* Added graph traversal support, and new "sort" and "random" streaming
expressions. It's also now possible to create streaming expressions with
the Solr Admin UI.
* Fixed the ENUM faceting method to not be unnecessarily rewritten to FCS,
which was causing slowdowns.
* Reduced garbage creation when creating cache entries.
* New [subquery] document transformer to obtatin related documents per
result doc.
* EmbeddedSolrServer allocates heap much wisely even with plain document
list without callbacks.
* New GeoJSON response writer for encoding geographic data in query
responses.
