Question

我的弹性文件如下

我想要满足条件的搜索查询： 如何获得具有AREA = Mumbai和AREA = Chennai的那些OPERATIONS和CATEGORY值

Answer 1

使用terms Query：

 {
  "query": {
    "terms": {
       "AREA": [
          "Mumbai",
          "Chennai"
       ]
      }
   }
 }

Answer 3

试试这个让我知道：

{
  "size": 0,
  "query": {
    "bool": {
      "should": [
        {
          "term": {
            "AREA": "mumbai"
          }
        },
        {
          "term": {
            "AREA": "chennai"
          }
        }
      ]
    }
  },
  "aggs": {
    "unique_operations": {
      "terms": {
        "field": "OPERATIONS",
        "size": 10
      },
      "aggs": {
        "count_areas": {
          "cardinality": {
            "field": "AREA"
          }
        },
        "top": {
          "top_hits": {
            "size": 2,
            "_source": {
              "include": ["CATEGORY"]
            }
          }
        },
        "areas_bucket_filter": {
          "bucket_selector": {
            "buckets_path": {
              "areasCount": "count_areas"
            },
            "script": "areasCount == 2"
          }
        }
      }
    }
  }
}

LATER EDIT ：添加top_hits聚合以获取涵盖类别请求的示例文档。
