the form gets posted and you construct and redirect to the search engine...
so.. let's take google.com as an example... you go to the site, type text in the box, click "find", notice that the URL is: http://www.google.com/search?hl=en&q=snitz+forum , where the text in green is what you search on ( "+" is for spaces in a URL line )
if you need me to write the ASP code, i'll take the 3 mins to do it.. just post that you need it
isn't that the same thing as the supersearch mod that can be downloaded at forumsquare.com?
Oops, I hit the post button too quickly... If I'm correct, that search mod allows you to choose from several different search engines so you can give your visitors more freedom.
