弹性搜索结合聚合

Question

目前下面的查询删除了单个字段上的重复项 - "name"，但我们需要所有字段的 top_hits 个结果："name"、"venueName"、"venueTown".这是否可以在一个查询中实现而不发送 3 个请求并将 "field" 设置为 "venueName" 和 "venueTown"?

{
  "aggs": {
    "query": {
      "terms": {
        "field": "name"
      }
     ,
      "aggs": {
        "top": {
          "top_hits": {
            "size": 1
          }
        }
      }
    }
  },
    "size": 0,
  "query": {

          "multi_match": {
            "query": "LAURA",
            "operator": "OR",
            "fields": [
              "name",
              "venueName",
              "venueTown"
            ]
          }
  }
}

如果我没理解错的话，你可以编写多个具有热门点击的聚合。

{
  "query": {
    "multi_match": {
      "query": "LAURA",
      "fields": [
        "name",
        "venueName",
        "venueTown",
      ]
    }
  },
  "aggs": {
    "name": {
      "terms": {
        "field": "name"
      },
      "aggs": {
        "top": {
          "top_hits": {
            "size": 1
          }
        }
      }
    },
    "venue_name": {
      "terms": {
        "field": "venueName"
      },
      "aggs": {
        "top": {
          "top_hits": {
            "size": 1
          }
        }
      }
    },
    "venue_town": {
      "terms": {
        "field": "venueTown"
      },
      "aggs": {
        "top": {
          "top_hits": {
            "size": 1
          }
        }
      }
    }
  }
}
