es是否可以对一组词按出现在次数进行排序

这个查询是找出匹配记录的TOP5的词，但是否可以只统计固定的某组词的词频



类似 ：select word, count(*) as cnt from table_name where word in ('a', 'b', 'c', 'd') group by word order by cnt desc LIMIT 10

​{

    

    "query": {

        "bool": {

            "must": [

                {"terms": {"content": ["word"]}}

            ]

        }

    },

    "aggs": {

        "top5": {

            "buckets": { "field" : "content","size":5 }

        }

    }

}
