How to rewrite /page/x?q=query to /page/x

Little update on this if someone has the same error:

This will redirect the query q=*anything* to index.php
RewriteCond %{QUERY_STRING} q=(.*)
RewriteRule ^(.*)$ $1? [L,NC,R=301]

This will already help, but I want to redirect it to the correct page instead of index.php

Also put this into robots.txt (unconfirmed)
Disallow: /page/*?*
Disallow: /page/*?q=*
Allow: /page/*

This could possibly block all /page/ sites.. I’m still testing this. If Google works as I think it does it should index all /page/1 /page/2/ but not /page/1?q=query

I’m slowly starting to understand mod_rewrite rules. Here are the final rules that I put together:

Final rules
RewriteCond %{QUERY_STRING} ^[A-Za-z0-9-]=(.*)
RewriteCond %{REQUEST_URI} /page/[0-9]/?
RewriteRule ^(.*) $1? [L,NC,R=301]

Put above:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

I use two conditions,
(1) whenever there is a query string using letters or characters a-z
(2) whenever the requested URI is /page/number between 1-999)
then rewrite to last $1 request permanently

I’ll probably remove the lines from robots.txt ..and I might change the second condition to remove all query strings after verifying that I don’t need them.
