Looking for a Simple Regex

Hey there, I was looking for a simple regex for

http://www.example.com/book-store?par=x

where anything can go after the question mark (parameter setter) to redirect to same paramaters just

http://www.example.com/store?par=x

Should be simple enough, sorry I don't know rewrites yet!

Take care,
Lance

 

RewriteEngine on
RewriteRule ^book-store$ store?%{QUERY_STRING}

Code (markup):

That simply changes book-store to store and attaches the original query.
