查询或过滤最小字段值？

也许您可以结合热门匹配来尝试：

GET user/tests/_search?search_type=count{  "aggs": {    "users": {      "terms": {        "field": "user",        "order": {          "_term": "asc"        }      },      "aggs": {        "lowest_score": {          "min": { "field": "score"          }        },        "agg_top": {          "top_hits": {"size":1}        }      }    }  },  "size": 20}
