Search across fields

Use case:
The operator ( - ) doesn't work. And the NOT either. Example: When I do a filter and would write something like that in the query : gmap -jesse I would expect to have all the comments / description / summary with the word MAP and WITHOUT the word jesse to come out. I tried like GMAP NOT JESSE and GMAP -"approved by jesse", but it never check my ( - ) or NOT.

Thanks.
