1.去重

{
    "size" : 0,
    "aggs" : {
        "distinct_colors" : {
            "cardinality" : {
              "field" : "去重的字段名"
            }
        }
    }
}

2.聚合 

根据颜色字段计算 每个桶下的个数

{
    "size" : 0,
    "aggs" : { 
        "popular_colors" : { 
            "terms" : { 
              "field" : "color"
            }
        }
    }
}

 

3.先按性别分桶 然后再根据性别下查看有几重颜色 (去重)

{
  "query": {
    "bool": {
      "should": [],
      "must_not": [],
      "must": [
        {
          "range": {
            "createAt": {
              "gt": "2020-07-09T15:25:00.000+0800",
              "lt": "2020-07-09T15:25:00.200+0800"
            }
          }
        }
      ]
    }
  },
  "sort": [],
  "aggs": {
    "all_brasname": {
      "terms": {
        "field": "brasname.keyword"
      },
      "aggs": {
        "distinct_stbid": {
          "cardinality": {
            "field": "stbid.keyword"
          }
        }
      }
    }
  }
}
