ElasticSearch实现GroupBy多字段分组统计

需求描述

对clientip，request，vhost 三个字段进行group by分组统计count，之后根据传入的时间进行区间筛选。
转换成对应的sql应该是

select
	MAX(@timestamp) as accessTimeStamp, 
	clientip as clientIp, request, 
	vhost, count(*) AS accessCount 
from  nginxweb-2022-08-17 
where  @timestamp  between '2021-08-17T00:24:41.000Z' 
and '2023-08-17T00:25:00.000Z' 
GROUP BY
