CodeIgniter urls

Hello,

I would just like some clarification on the CodeIgniter url module. If I developed a simple search form in standard php using the GET method, I would get a standard query string such as

http://localhost/index.php?id=2

. If I did the same in CodeIgniter, would it automatically rewrite the url to something like

http://localhost/index.php/welcome/search/2

.
