Search (not a view) where a field is not empty

Search (not a view) where a field is not empty

Is there a way to do a search where a field "is not" ${EMPTY}? This is possible when creating a custom view, but "is not" ${EMPTY} doesn't seem to be an option or possible in a search. What I'm trying to do is a search where the phone or email "is not" ${EMPTY}. I also tried using some wildcards like "*" and "%".
