如何仅针对一种类型的记录查询elasticsearch？

I am issuing a query to elasticsearch and I am getting multiple record types. How do I limit the results to one type?

我正在向elasticsearch发出一个查询，我正在获得多种记录类型。如何将结果限制为一种类型？

The following query will limit results to records with the type "your_type":

以下查询将结果限制为类型为“your_type”的记录：

curl - XGET 'http://localhost:9200/_all/your_type/_search?q=your_query'

curl - XGET'http：// localhost：9200 / _all / your_type / _search？q = your_query'

See http://www.elasticsearch.org/guide/reference/api/search/indices-types.html for more details.

有关详细信息，请参阅http://www.elasticsearch.org/guide/reference/api/search/indices-types.html。

You can also use query dsl to filter out results for specific type like this:

您还可以使用查询dsl过滤掉特定类型的结果，如下所示：

$ curl -XGET 'http://localhost:9200/_search' -d '{
    "query": {
        "filtered" : {
            "filter" : {
                "type" : { "value" : "my_type" }
            }
        }
    }
}
'

{
"query" : {
      "filtered" : { 
         "filter" : {
            "bool" : {
            "must" :[{"term":{"_type":"UserAudit"}}, {"term" : {"eventType": "REGISTRATION"}}]
           }
         }
      }
   },
   "aggs":{
      "monthly":{
         "date_histogram":{
            "field":"timestamp",
            "interval":"1y"
         },
         "aggs":{
            "existing_visitor":{
               "terms":{
                  "field":"existingGuest"
               }
            }
         }
      }
   }
}

"_type":"UserAudit" condition will look the records only specific to type

“_type”：“UserAudit”条件将查看仅特定于类型的记录

On version 2.3 you can query _type field like:

在版本2.3上，您可以查询_type字段，如：

{
  "query": {
    "terms": {
      "_type": [ "type_1", "type_2" ] 
    }
  }
}

Or if you want to exclude a type:

或者，如果要排除类型：

{
  "query": {
    "bool" : {
      "must_not" : {
        "term" : {
          "_type" : "Hassan"
        }
      }
    }
  }
}
