It may exist for some things but in my database, I cannot search for members and exclude them based on a particular email address. Example: I want to send an email to everyone who is not on AOL. So I try to search for "does not contain" @aol.com but I can't do it.

It may be a poor example but it is the simplest to get the idea across. I'd like to see the "does not contain" and "is not" values in the advanced search. I have found several instances where I could have used that feature but couldn't search the way I'd like.  Thanks.
