dynamic URL result in search?

I've been plugging away at learning a bunch about PHP, but now I'm stuck. I've found a search utility at http://www.digitalgenesis.com/software/dgssearch.html , and I was able to go through and customize it. But then I came upon the problem of correct URL's for the search results. I just learned to do the 'test.php?start=3' thing (ie. dynamic pages based on query strings), and now I'm working on creating URL's for the search results that will work properly. Getting a URL that consists of just a category [ie. books.php] isn't a problem. That's a matter of accessing the 'category' in the database. But, because I have a few pages of books, I need to get users to the page their book is on [books.php?page=3] -- else they'll have to try to find the book they searched for by going through a bunch of pages. Any suggestions or online resources [tips/tutorials] would be greatly appreciated! I've looked, but can't seem to find anything. Thanks Rita
