ElasticSearch 基于Lucene的搜索引擎
ElasticSearch是一个基于Lucene构建的开源，分布式，RESTful搜索引擎。设计用于云计算中，能够达到实时搜索，稳定，可靠，快速，安装使用方便。支持通过HTTP使用JSON进行数据索引。
我们建立一个网站或应用程序，并要添加搜索功能，令我们受打击的是：搜索工作是很难的。我们希望我们的搜索解决方案要快，我们希望有一个零配置和一个完全免费的搜索模式，我们希望能够简单地使用JSON通过HTTP的索引数据，我们希望我们的搜索服务器始终可用，我们希望能够一台开始并扩展到数百，我们要实时搜索，我们要简单的多租户，我们希望建立一个云的解决方案。Elasticsearch旨在解决所有这些问题和更多的。
Elasticsearch 6.0.1 已发布，Elasticsearch 是一个分布式的 RESTful 风格的搜索和数据分析引擎。
