Elasticsearch - 按字段获取结果摘要

问题描述

{"name": "John","district": 1,"light": 2},{"name": "John","district": 5,"light": 27},"district": 11,"light": 1},"light": 0},"light": 10},"district": 8,"light": 6},{"name": "Mary","district": 2,{"name": "Nick",{"name": "Bob","district": 3,{"name": "Kenny","light": 8}

按名称字段搜索时，如何按组数获取剩余字段的摘要？

示例：

搜索时

  "query": {
    "term": {
      "name": {
        "value": "john"
      }
    }
  }

预期输出：

{
  "district": {
    11: 3,// value : the amount of matches
    5: 2,1: 1,},"light": {
    2: 2,// value : the amount of matches
    27: 1,10: 1,// etc..
  }
}

解决方法

尝试一对术语聚合：

{
  "size": 0,"query": {
    "term": {
      "name": {
        "value": "john"
      }
    }
  },"aggs": {
    "by_district": {
      "terms": {
        "field": "district"
      }
    },"by_light": {
      "terms": {
        "field": "light"
      }
    }
  }
}
