注：7.0之后，type默认都是_doc

创建文档

elasticsearch创建文档有两种方式，1是POST，2是PUT，post是让elasticsearch自动生成id，而通过put，我们可以自己指定id

自动生成id

POST my_index/_doc { "username": "pibigsrar" "age": 12 }

自定义id

指定id为1（如果id已经存在，则直接报错）

PUT my_index/_doc/1?op_type=create { "username": "pibigsrar" "age": 12 }

更新

删除并更新

它会先删除原先id为1的文档，并把新的文档设置进去

PUT my_index/_doc/1 { "username": "pibigsrar" }

只更新

你可以通过这个新增一个字段或修改某个字段的值

POST my_index/_update/1 { "doc": { "username": "test" "sex": 1 } }

删除

DELETE my_index/_doc/1

读取

GET

根据id获取

GET my_index/_doc/1

bulk

批量执行操作，操作可以是查询，创建，删除，搜索等

POST _bulk { "index" : { "_index" : "test", "_id" : "1" } } { "field1" : "value1" } { "delete" : { "_index" : "test", "_id" : "2" } } { "create" : { "_index" : "test2", "_id" : "3" } } { "field1" : "value3" } { "update" : {"_id" : "1", "_index" : "test"} } { "doc" : {"field2" : "value2"} }

mget

批量获取

GET my_index/_mget { "docs" : [ { "_id" : "1" }, { "_id" : "2" } ] }

不同的index

GET /_mget { "docs" : [ { "_index" : "my_index", "_id" : "1" }, { "_index" : "test", "_id" : "2" } ] }

msearch

批量搜索

POST my_index/_msearch {} {"query" : {"match_all" : {}},"size":1} {"index" : "kibana_sample_data_flights"} {"query" : {"match_all" : {}},"size":2}

去重

根据contentId 去重

"aggs": { "distinct_contentId": { "cardinality": { "field": "contentId", } } }

分组

根据contentId分组count

"aggs": { "label_group": { "terms": { "field": "contentId" } } }
