title: fat free: how to specify a query string in route
body: <p>In Fat Free Framework, I am trying to figure out how to specify a query string  in the route call or the routes.ini file. </p>
  
  <p>I want to be able to decode a route specified like this</p>
  
  <p><a href="http://example.com/search?category=22&amp;term=wide" rel="nofollow noreferrer">http://example.com/search?category=22&amp;term=wide</a></p>
  
  <p>Note if possible I'd like to have a varying number of elements in the query string.</p>
  
  <p>Thanks in advance</p>
