How to make htaccess redirect without GET parameters?

Question

htaccess

Good afternoon everyone!
Can you please tell me how to make a redirect from the main page with GET parameters to the main one, but without GET parameters (as in the example below)?
For example:

http://site.ru/?q=444 => http://site.ru/
или 
http://site.ru/index.html?q=444 => http://site.ru/index.html

The rest of the pages should work as usual.
Thanks in advance!

End the second parameter of the RewriteRule with a question mark:
RewriteRule ^(.*)$ $1?
