I'm trying to set up a tab showing latest questions tagged with A or B but not C, but there doesn't seem to be any way to get this to work?
Some things I've tried:
[A] [B] not [C]shows everything (presumably it assumed "
or not [C]").
[A] [B] and not [C]is exactly the same as
[A] or [B].
And sometimes, while trying to edit the query, the results lock up with no results and won't update any more - but that's a separate issue.
