}

I am using above query but it takes too much time to execute. There are about 1900000 events. How can i optimize above query? should I use filter ?

Hi @rupal,

you can use the [profile API](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-profile.html) (available in ES 2.2+) to dig deeper. I **guess** your problem are the aggregations.
