htaccess problems

[eluser]St0neyx[/eluser]
Hi,

I'm not that good with htaccess files so i copied mine from the forum.

my htaccess code

Code:

RewriteEngine on
RewriteCond $1 !^(index\.php|css|font|images|includes)
RewriteRule ^(.*)$ /index.php/$1 [L]

This code makes the index.php disapear from the url.
example
www.site.com/index.php/controller/function/segments
after htaccess
www.site.com/controller/function/segments

now i also want this in my url
www.site.com/controller?blaat=blaat

this is not accepted, how can i make this acceptable?
in the config ? is an allowed char for the url.

I don't want to piss people off, but dont come with solutions like
why don't u just do www.site.com/controller/blaat
because thats not what i need..
