我有一个包含类别数组的产品集合。我需要的是聚合(?)—一个不同类别id的数组。也很高兴有-计数匹配的产品编号每个类别的标识。
样本索引数据

{
  "data": [
    {
      "took": 6,
      "timed_out": false,
      "_shards": {
        "total": 1,
        "successful": 1,
        "skipped": 0,
        "failed": 0
      },
      "hits": {
        "total": 4257,
        "max_score": 1.0,
        "hits": [
          {
            "_index": "index_name",
            "_type": "product",
            "_id": "4",
            "_score": 1.0,
            "_source": {
              "entity_id": "4",
              "attribute_set_id": "4",
              "type_id": "simple",
              "sku": "skuxxx",
              "has_options": false,
              "required_options": false,
              "created_at": "2020-01-29 06:38:52",
              "updated_at": "2020-09-04 12:31:00",
              "visibility": "4"
            },
            "category": [
              {
                "category_id": 2,
                "is_virtual": "false"
              },
              {
                "category_id": 3,
                "is_parent": true,
                "is_virtual": "false",
                "name": "Category name1"
              },
              {
                "category_id": 4,
                "is_parent": true,
                "is_virtual": "false",
                "name": "Category name2"
              },
              {
                "category_id": 7,
                "is_parent": true,
                "is_virtual": "false",
                "name": "Category name3"
              }
            ]
          }
        ]
      }
    }
  ]
}

我需要的是类别ID数组,按产品计数和筛选类别的可能性排序( "is_virtual" 或者 "is_parent" ):
预期结果

{
  "data": [
    {
      "categories": [
        {
          "category_id": 2,
          "doc_count": 555
        },
        {
          "category_id": 3,
          "doc_count": 150
        },
        {
          "category_id": 56,
          "doc_count": 12
        }
      ]
    }
  ]
}
