It isn't very obvious to new users that the Super Search exists to search node content. It may not even be obvious that the default search isn't this type of search. Making it clear that this search exists would help people help themselves.
One place to add it might be at the bottom of the standard search return for multiple results, near the CPAN search. Another place could be in the title-bar near the default search. The Perl Monks FAQ and the Site How To could make mention of it.
