Yes, but when the user chooses two of the 'same' option (say Windows and FreeBSD on your site) then the search should find links that have both these options, not either of these options. That's how the admin panel search works but it doesn't seem to work that for me with search.cgi, or the original poster if they are still around .

I might look around at a few other Links sites and see if I can work out what's going on. If I can't I'll get back to you as you have a pretty complex search form and there's probably something in there I can learn from.
