ES操作看这一篇就够了

【go封装的操作还是得看作者的】

1、创建空索引

PUT /online
curl -H "Content-Type: application/json" -X PUT --data '{"settings":{"index":{"number_of_shards":2,"number_of_replicas":"0"}}}' 172.17.0.2:9200/user

2、删除索引

DELETE /online
curl -v -X DELETE 172.17.0.2:9200/online

3、插入数据

curl -H "Content-Type: application/json" -X POST  --data '{"doc":{}}}' http://localhost:9200/online/table
curl -H "Content-Type: application/json" -X POST  --data '{"user_name":"tang","records":{}}' http://172.17.0.2:9200/user/user

4、更新数据

POST /online/table/qqqqqqqqqq   可以直接覆盖
curl -H "Content-Type: application/json" -X POST  --data '{"doc":{"bbb":["Bdd1","gg"]}, "detect_noop": false}' 172.17.0.2:9200/user/user/c6d8c084-86ad-440a-8efb-3ad3bd3cc669/_update
curl -H "Content-Type: application/json" -X POST  --data '{"script" : "ctx._source.applys.remove(\"3c1f7c0a-be92-4797-abdd-23ff7b0401df\")"}' 172.17.0.2:9200/user/user/40435324-57da-4d75-99e8-6fa69d3ef15f/_update
局部更新

5、删除数据

DELETE /online/table/qqqqqqqqqq
curl -v -X DELETE 172.17.0.2:9200/online/table/5a0443bb-4cbc-4614-9f65-48eecb6d48fc
curl -v -X DELETE 172.17.0.2:9200/user/user/_junxHAB9FugYMT7hGtV

6、搜索数据

GET /online/table/qqqqqqqqqq                 			单条数据
GET /online/table/_search                    			全部数据 默认返回10条
GET /online/table/_search?q=name:"新建文档"   			关键字搜索
GET /online/table/qqqqqqqqqq?_source=id,name			只返回这两个字段的信息
GET /online/table/qqqqqqqqqq/_source		  			只返回元数据信息
GET /online/table/qqqqqqqqqq/_source?_source=id,name 	只返回这两个字段的元数据信息

curl -v 172.17.0.2:9200/online/table/b05e85ba-d09e-4eee-b119-418d87f534c1
curl -v 172.17.0.2:9200/user/user/40435324-57da-4d75-99e8-6fa69d3ef15f
curl -v 172.17.0.2:9200/user/user/_search

DSL 搜索

POST /online/table/_search

_index = 数据库
_type = 表
_id 与上面两个组合，唯一标识一个文档

是否存在

HEAD /online/table/qqqqqqqqqq   查看响应码

7、批量操作

POST /online/table/_mget
{
	"ids":["1001","1003"]
}
 局部更新 ： /haoke/user/1001/_update https://www.bilibili.com/video/av67957955?p=10
 关键字搜索： /haoke/user/_search?q=name:tang
 DSL 搜索： /haoke/user/_search POST 请求
 	{"query":{
 		"match":{
 			"age":21
 			}
 		}
 	}
