主要是提供一些搜索服务客户端，比如常见的 Elasticsearch、solr

Elasticsearch

Elasticsearch 是当前比较流行的 搜索框架，这里提供两个库，第三方和官方的，特点各有千秋。

• 官方 https://github.com/elastic/go-elasticsearch star: 2700+
• 第三方https://github.com/olivere/elastic star: 5300+

第三方的这个已经不在维护，所以推荐使用官方的

Compatibility

The client major versions correspond to the compatible Elasticsearch major versions: to connect to Elasticsearch 7.x, use a 7.x version of the client, to connect to Elasticsearch 6.x, use a 6.x version of the client.
