What kind of query are you running?  
Are you using `doc_values` (I guess no)?

Unable to debug as to which query caused it as our application has many APIs querying Elasticsearch and queries aren't logged into the logs.

doc\_values is true by default on all the fields I guess...!!

Can you share the mapping?
