Just assign the $_POST[] vars to session vars:
in your form instead of using a search.php(for instance) file as the actiuon
use a redirect.php.
This redirect.php file just reads the $_POST['q'] (q is the query variable)
and assigns it to a session var, then it redirects to search.php.
in search.php you just read the session var and post the results. In this
way if the user hits the back button, he will be sent to search.php and the
session var is always available.
