We've made some changes to the website including several url's. Since some other websites haven't updated their forms/url's yet they are linking to the wrong page. We've come up with the RewriteRule you can find in the Code Snippet, but it's not working at all.

And most of the time it has &button=Search at the end of it.

RewriteRule ^search/\?keywords=([^&]*)(?:&place=([^&]*))?.*$ search.php?s=$1&p=$2 [R=301,NC]
# Some other rules.
