Query string + hash fragment combo

This page combines a query string with a hash fragment. The full URL looks like /hash-query-combo/?q=test#results. The ?q= parameter is processed server-side; the #results fragment scrolls the page to the results section. A crawler must parse ? before # to correctly extract the query parameters — if it treats everything after # as the fragment, it will miss ?q=test; if it treats #results as part of the query string, it will send a malformed request.
