我发现的唯一接近的事情是：Elasticsearch中的多个分组方式

基本上，我试图获得与以下MySql查询等效的ES ：

select gender, age_range, count(distinct profile_id) as count 
FROM TABLE group by age_range, gender

年龄和性别本身很容易获得：

{
  "query": {
    "match_all": {}
  },
  "facets": {
    "ages": {
      "terms": {
        "field": "age_range",
        "size": 20
      }
    },
    "gender_by_age": {
      "terms": {
        "fields": [
          "age_range",
          "gender"
        ]
      }
    }
  },
  "size": 0
}

这使：

{
  "ages": {
    "_type": "terms",
    "missing": 0,
    "total": 193961,
    "other": 0,
    "terms": [
      {
        "term": 0,
        "count": 162643
      },
      {
        "term": 3,
        "count": 10683
      },
      {
        "term": 4,
        "count": 8931
      },
      {
        "term": 5,
        "count": 4690
      },
      {
        "term": 6,
        "count": 3647
      },
      {
        "term": 2,
        "count": 3247
      },
      {
        "term": 1,
        "count": 120
      }
    ]
  },
  "total_gender": {
    "_type": "terms",
    "missing": 0,
    "total": 193961,
    "other": 0,
    "terms": [
      {
        "term": 1,
        "count": 94799
      },
      {
        "term": 2,
        "count": 62645
      },
      {
        "term": 0,
        "count": 36517
      }
    ]
  }
}

但是现在我需要这样的东西：

[breakdown_gender] => Array
    (
        [1] => Array
            (
                [0] => 264
                [1] => 1
                [2] => 6
                [3] => 67
                [4] => 72
                [5] => 40
                [6] => 23
            )

        [2] => Array
            (
                [0] => 153
                [2] => 2
                [3] => 21
                [4] => 35
                [5] => 22
                [6] => 11
            )

    )

请注意，这0,1,2,3,4,5,6是针对年龄范围的“映射”，因此它们实际上表示的是:)而不是数字。例如，性别[1]（“男性”）细分为[246]的年龄范围[0]（“18岁以下”）。
