Best way to implement search?

[eluser]Mateo1041[/eluser]
Here's my dilemma:

* I want to use form validation
* I want the user to be able to bookmark the search results page or share with friends

What's the best way to go about this? CodeIgniter doesn't support GET, so I'm not able to pass parameters via the URL line by default. I tried the following, but it didn't work:

I could use JavaScript to rewrite the action when the submit button is pressed, but then I don't see a good way to use form validation. :-( On the other hand, I'd hate to get rid of form validation because the rest of my website already uses it and I'd like to be consistent.

Any recommendations would be greatly appreciated.
