mutt makes a server-side search when the search operator starts with "=" instead of "~"; this also means that it is a string search rather than a regexp search, if I understand correctly this is due to the IMAP protocol search not supporting regexps. So e.g. "=s f.o" makes a server-side search for the exact string "f.o" in the subject, but "~s f.o" makes a client-side search in subject for f, then any character, then o.
