URGENT! small fix

I need someone to fix the search feature on my site. If you click on the "Search" tab & try to do a search either for males or females, there are no results. It just says: No results found. Start again and try to broaden your search. The site has several thousand members, so that must be fixed. This a quick fix for someone who knows PHP. It is a dating site running on the old Boonex software. [login to view URL] This is urgent & needs to be done right away. Upon completion of this small project, I have more projects that we can discuss. Thank you
