You can eliminate searching particular labels by using: -label:Name
GMail indexes email headers, so one can search by date: "Tue, 14 Dec 2004" or email address yourname@example.com
However, GMail does not recogonize the @ symbol as being a particular character, so you can't search for all email from a particular domain like @gmail.com.
Also, the "Reply-To" and "To" searches don't usually work as you're searching for exact text and not a field.
Is there a way to search just one field? (To=?)
Is there a way to just search one conversation?
