DSL查询

查询指定记录

GET index_name/_search
{
	"query":{
		"term":{
			"businessId":{
				"value" : #{id}
			}
		}
	}
}

查询全部

GET index_name/_search
{
  "query":{
    "match_all": {
    }
  }
}

使用sql进行查询 format类型有：json,yaml,smile,cbor,txt,csv,tsv

POST /_index_name/sql?format=txt
{
  "query":"select * from index_name where id = 2"
}

DSL删除

删除单条数据

POST index_name/_delete_by_query
{
  "query": {
    "term": {
      "id": {
        "value": "6379"
      }
    }
  }
}

删除全部数据

POST index_name/_delete_by_query
{
  "query":{
    "match_all": {
    }
  }
}

DSL修改

将id=6379的数据的auditState修改为'2100'

POST index_name/_update_by_query
{
  "query": {
    "term": {
      "id": {
        "value": "6379"
      }
    }
  },
  "script":{
    "inline": "ctx._source['auditState']='2100'"
  }
} 

ES中的随机排序

"sort": [{
        "_script": {
            "script": {
                "source": "Math.random()",
                "lang": "painless"
            },
            "type": "number",
            "order": "asc"
        }
    }]

ES 查询不存在的某个字段

{
	"bool": {
		"must_not": [{
			"exists": {
				"field": "proGroupType",
			}
		}]
	}
}
