is it a question?
anyway, I posted long time ago, that if u change <form method="post" to <form method="get" in search.html template, then it will display all the address queries (is it correct word to call stuff following after " ? " in the address?) in the address bar.
Why would u want that?
well, few reasons:
1. u can send to your friend the results of search.
2. if u use site loggin system, it will log what users where search for, well, atleast the address with all queries.
