Terms Aggregation 根据字段值分组聚合

 SELECT field,count(*) FROM db GROUP BY field

使用aggs中的terms来实现分组查询{  "aggs": {    "group_yy": {      "terms": {        "field": "domain"      }    }  }}


POST /bank/_search?size=0
{
  "aggs": {
    "age_terms": {
      "terms": {
        "field": "age"
      }
    }
  }
}
