capture rewrite for every after question mark

[token]

Hello,

   I have found the following while searching it is the only one i can
get working with my config setup
   to send a 301 permanently if "/index.php" is directly accessed.


    if ($request_uri ~* ^(/home(/index)?|/index(.php)?)/?$)
    {
    rewrite ^(.*)$ / permanent;
    }


   GET http://www.example.com/index.php 301 Moved Permanently
   GET http://www.example.com/  200 OK

   ---------------------------------------
   above works as expected.
   
   But, now if i have the following results as 200 OK as expected.

   http://www.example.com/index.php?randomvalue  200 OK


   So how do you rewrite that if there is a question mark and or value
that follows "/index.php?" then returns 301.

   GET http://www.example.com/index.php?randomvalue  301 Moved
Permanently

   GET http://www.example.com/  200 OK
