Are you talking about the message at the bottom of the search page? Where it says "Dissatisfied? Help us improve"?
You can enter comments and enter a url:
"Were you looking for a specific URL that wasn't listed in the search results? If so, please enter the URL here:"

and it appears at the bottom for "britney" :) as well as more obscure searches.
