I did check and see if this was suggested prior, but it does not seem so. People suggest more filters, but not specifically dorks or search operators like you would use on a normal search engine.

For example, say you would want to search for emails from GOG, and you want to delete them, but you want to keep the newsletters. You might want to search "GOG -news" and this would remove all results that have "news", ideally removing all of the newsletters from the results.

I think this would be a relatively easy feature to implement and would significantly help people with larger inboxes.

The operators that would be useful in such a context would be: exclude (-), include (+), the use of quotes to find exact match, single character wildcards, and boolean operators ("|").

And please dont make this a paid feature, either. I know this doesn't need to be paid, I know it can be implemented in a day. Charge for all the filters or whatever, but don't charge for this, that would be legitimately scummy to do as literally every search engine allows one to do this for free–it is a basic and universal feature.
