按类型限制ElasticSearch聚合？ [英] Restrict ElasticSearch aggregation by type?

问题描述

如何针对特定类型执行ElasticSearch聚合？我意识到您可以在请求Url中指定索引和/或类型，但是我想在两种不同类型上执行聚合。

How do you perform an ElasticSearch aggregation for a specific type? I realize that you can specify the index and/or type in the request Url, but I want to perform aggregations on two distinct types.

谢谢！

推荐答案

您可以按类型过滤聚合，然后使用子聚合。例如：

You could filter the aggregation by type, and then use sub-aggregations. For example:

{
  "aggs": {
    "Test 1": {
      "filter": {
        "type": {
          "value": "type1"
        }
      },
      "aggs": {
        "agg_name": {
          "terms": {
            "field": "field1",
            "size": 10
          }
        }
      }
    },
    "Test 2": {
      "filter": {
        "type": {
          "value": "type2"
        }
      },
      "aggs": {
        "agg_name": {
          "terms": {
            "field": "field2",
            "size": 10
          }
        }
      }
    }
  }
}
