So I am missing something obvious. I want to find all items that do not have a tag. !@ or not @ does not work. Is this possible?
There isn’t a way to do do this directly right now. Instead you need to do a text based search. So for example you could do:
not "@"
To find all items that don’t contain the “@” character … though that would miss items that have no tags, but do have an email address. You can get more fancy with matches and regular expressions:
not matches "($|\\s)@\\w+"
