In the advanced search filters you are only able to include criteria (spaces, users, etc).

It would be very helpful to be able to filter out criteria as well, where you can exclude search results by those same criteria (spaces, users, etc).

For example, "not" in space XYZ, or "not" modified by user "ABC".

Note: I did search the tickets for this but didn't find any. I also tried to put this into the CONFCLOUD project but was unable to.
