CSRF makes problem on search page

thanks for reply,

I didn't get what i wanted, maybe i did wrongly.
here is what i did:

PHP Code:

$config['csrf_exclude_uris'] = array('http://localhost/index.php/search/results'); 


But seems CSRF still is enable for my search form!

what I'm doing is:
(page1) Search1: test one
(page2) Search2: test two

when i go back to the search1 page by clicking on the previous button on browser, now i wanna search again:
(page1)Search3: test tree
Then ill get this:

Code:

An Error Was Encountered
The action you have requested is not allowed.

what i need is the search box working without CSRF and login link works with CSRF !
