搜索
[root@localhost ~]# curl localhost:9200/book/group/_search?q=es&size=1
[1] 85817
[root@localhost ~]# {"took":1,"timed_out":false,"_shards":{"total":1,"successful":1,"skipped":0,"failed":0},"hits":{"total":{"value":2,"relation":"eq"},"max_score":0.5442147,"hits":[{"_index":"book","_type":"group","_id":"2","_score":0.5442147,"_source":{"name": "es study","organizer": "andy"}},{"_index":"book","_type":"group","_id":"1","_score":0.4700036,"_source":{"name": "es in action","organizer": "bob"}}]}}
[1]+  完成                  curl localhost:9200/book/group/_search?q=es

搜索返回部分字段
curl localhost:9200/book/_search?pretty&q=es&fields=name,ext&size=1

在部分字段中搜索
curl localhost:9200/book/_search?pretty&q=name:es&size=1

多个索引中搜索
curl localhost:9200/book,otherIndex/_search?pretty&q=es
全部索引中查找：不推荐
curl localhost:9200/_search?pretty&q=es

也可使用json指定搜索条件，实现一些更加复杂的查询
curl localhost:9200/book/_search 
> -d '{"query":{"query_string":{"query":"es"}}}' 
> -H "Content-Type: application/json"

更新文档
curl -XPOST localhost:9200/book/group/1/_update -d '{"doc": {"ext": "update add ext"}}' -H "Content-Type: application/json"

关闭/打开索引
curl -XPOST localhost:9200/book/_close
curl -XPOST localhost:9200/book/_open
