When I go to the gmail web site and enter a search term, it searches through all my many years of mail, including inbox, sent, drafts, archived, etc. Apple Mail, and other clients (Airmail, MailPlane, MailTabPro) only search local mail - mail that's come in since I started using those apps (I used the late lamented Eudora for years). I have to go to the gmail site for a thorough search. Is this because I'm using POP? If I switched to Imap, would these clients search everything on the server? If not, is there any way to do a complete mail server search via a local client?
