热门搜索中的弹性搜索过滤器

Question

我在ES中有如下数据。我希望结果集具有部门1，因此只有位置55和60应该出现，而区域销售应该具有所有部门的总和$ 550。任何想法如何实现以上。非常感谢！

DivNbr |区| Locn |销量

1 | 616 | 55 | $ 100

2 | 616 | 61 | 200美元

1 | 616 | 60 | $ 250

  "by_district_id": {
    "terms": {
      "field": "district"
   },
  "aggs": {
      "top_session_hits": {
        "top_hits": {

            "includes": [
              "locn",
              "sales"
             ]
          }
       }
      },
      "dist_sls": {
        "sum": {
          "field": "sales"
        }
      }
   }
  }
}

}

您可以添加Filter Aggregation，以便只有division 1可用的结果。

下面是查询及其示例响应
