新建索引

curl -XPUT 'http://localhost:9200/dept/employee/1' -d '{ "empname": "emp1"}'

删除数据

curl -XDELETE 'http://localhost:9200/dept/employee/3'

查询所有数据

curl http://localhost:9200/dept/employee/_search?pretty=1 -d '{"query":{"regexp":{"empname":{"value":".*"}}}'

1. create:  

指定 ID 来建立新记录。 (貌似PUT, POST都可以) 
$ curl -XPOST localhost:9200/films/md/2 -d ' 
{ "name":"hei yi ren", "tag": "good"}' 

使用自动生成的 ID 建立新纪录: 
$ curl -XPOST localhost:9200/films/md -d ' 
{ "name":"ma da jia si jia3", "tag": "good"}' 

2. 查询: 
2.1 查询所有的 index, type: 
$ curl localhost:9200/_search?pretty=true 

2.2 查询某个index下所有的type: 
$ curl localhost:9200/films/_search 

2.3 查询某个index 下, 某个 type下所有的记录: 
$ curl localhost:9200/films/md/_search?pretty=true 

2.4 带有参数的查询:  
$ curl localhost:9200/films/md/_search?q=tag:good 
{"took":7,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":2,"max_score":1.0,"hits":[{"_index":"film","_type":"md","_id":"2","_score":1.0, "_source" : 
{ "name":"hei yi ren", "tag": "good"}},{"_index":"film","_type":"md","_id":"1","_score":0.30685282, "_source" : 
{ "name":"ma da jia si jia", "tag": "good"}}]}} 

2.5 使用JSON参数的查询: (注意 query 和 term 关键字) 
$ curl localhost:9200/film/_search -d ' 
{"query" : { "term": { "tag":"bad"}}}' 

3. update  
$ curl -XPUT localhost:9200/films/md/1 -d { …(data)… } 

4. 删除。 删除所有的: 
$ curl -XDELETE localhost:9200/films
