Index warm up to speed up query time

Elastic Stack Elasticsearch

Thanks.

  1. To clarify, I am not so sure about the following statement in the official document. Would you mind to explain? Does this mean if my es query only involves full text search, using match, without bool filter (e.g. should, must ..etc.) will NOT work in cache?

"The query cache only caches queries which are being used in a filter context."

  1. Also, any suggestion of how to test efficiently if cache really works?

Thanks
