Possibility to use Operators together with Modifiers in Elastic Search

Hey,

In the current solution of Elastic Search it is possible to add Modifers like repo: and project: to limit the search. According to the documentation: https://confluence.atlassian.com/bitbucketserver/search-for-code-in-bitbucket-server-814204781.html.

If there are multiple modifiers in a query they are implicitly combined using "AND"

It would be awesome if this could be overridden by the user by using other Operators as well. One obvious use-case is to find a search string being able to exclude a project or repo, like:

"my search string" project:projA AND NOT repo:repoX

This would really take the search function in Bitbucket from good to great (or even ass-kicking)

Cheers,
