在 Elasticsearch 聚合关键字之上显示文本标签

Question

我有这个弹性聚合，但我想在 activity.kw 之上显示文本 activity.label。我知道这不仅仅是聚合，但我该怎么做呢？谢谢

GET /my-index/_search
{
  "size": 0,
  "query": {
    "match_all": {}
  },
  "aggs": {
    "group_by_state" : {
      "terms" : {
        "field" : "activity.kw",
        "size" : 3000
      }
    }
  }
}

今天我得到了类似的东西：

"aggregations" : {
    "group_by_state" : {
      "doc_count_error_upper_bound" : "0",
      "sum_other_doc_count" : "0",
      "buckets" : [
        {
          "key" : "0009",
          "doc_count" : "285396"
        },
        {
          "key" : "9090",
          "doc_count" : "1"
        }
      ]
    }
}

如果您尝试根据条款获取文档，您可以使用 top_hits 聚合。

查询

{
  "aggs": {
    "group_by_state" : {
      "terms" : {
        "field" : "activity.kw",
        "size" : 3000
      },
      "aggs": {
        "docs": {
          "top_hits": {            
            "_source": {
              "includes": [ "activity.label" ]
            },
            "size": 1
          }
        }
      }
    }
  }
}
