One could reproduce a similar effect by surrounding your query with double-quotes on Google. > Return search results by randomly selecting an exact string match from the index. It could potentially surface results that you could not have found otherwise. A random dump of links, each one's relevance you must determine on your own. Or another way to put it: you do the ranking. Not a very fun idea to most.
