The interesting thing about that page, of course, is that under the recent MGM v Grokster ruling, links like this are probably illegal in some cases:

http://google.com/search?q=%22Her+in...in%22&filter=0
http://google.com/search?q=%22frogli...ig%22&filter=0

While the underlying Google data remains completely legal. This is especially notable since the vast majority of the work done here is on Google's side (eg. the URLs comprise less than 100 characters, while Google has enormous databases on a huge amount of hardware dedicated to fulfilling this request).
