What about sending the form via POST, but to a URL that includes some
sort of session in the URL the form is sent to, for example:

<form action="page.php?sid=gsslgugckjeglktjb" method="post">

Then your server script can reproduce the search from saved parameters
stored under the sid value.

This way, you retain the ability to bookmark the search, and use as many
search parameters as you need, without worrying about going over the GET
data limit no matter what browser the user has.
