1、增加記錄

例如1：向指定的 /Index/Type 發送 PUT 請求，就可以在 Index 里面新增一條記錄。比如，向/accounts/person發送請求，就可以新增一條人員記錄。

curl -X POST 'localhost:9200/accounts/person/2' -d '{"user":"張三","title": "工程師","desc":"系統管理"}'

　　系統提示如下錯誤：

{"error":"Content-Type header [application/x-www-form-urlencoded] is not supported","status":406}

　　

需要制定插入數據格式：如下

curl -H "Content-Type: application/json" -X POST 'localhost:9200/accounts/person/2' -d '{"user":"張三","title": "工程師","desc":"系統管理"}'

系統提示：

{"_index":"accounts","_type":"person","_id":"2","_version":1,"result":"created","_shards":{"total":2,"successful":1,"failed":0},"_seq_no":0,"_primary_term":1}

　　說明插入成功

例如2：

curl -H "Content-Type: application/json" -X PUT 'localhost:9200/accounts/person/4' -d '{"user":"李四","title": "軟件工程師","desc":"系理集成"}'

　　系統提示：

{"_index":"accounts","_type":"person","_id":"4","_version":1,"result":"created","_shards":{"total":2,"successful":1,"failed":0},"_seq_no":1,"_primary_term":1}

說明插入成功。

?

可以使用PUT、POST插入數據，需要制定插入數據的數據格式，用?-H "Content-Type: application/json"制定為json格式。

2、數據查詢

curl 'localhost:9200/accounts/person/4?pretty'

系統返回：

{"_index" : "accounts","_type" : "person","_id" : "4","_version" : 1,"found" : true,"_source" : {"user" : "李四","title" : "軟件工程師","desc" : "系理集成"} }

說明查詢成功。如果查詢一個不存在id的記錄，如命令：

curl 'localhost:9200/accounts/person/5?pretty'

id等于5的person因為沒有對應的記錄，所以，系統返回：

{"_index" : "accounts","_type" : "person","_id" : "5","found" : false }

?

3、刪除記錄

刪除記錄就是發出 DELETE 請求。
