google does strange things, often when it says such and such word is common and was not included in your search, remove that word and the search results are different !
I'll post an example later

Edit an easy one, search for the game, 'live for speed'
http://www.google.com/search?hl=en&i...=Google+Search
notice it says for was not included in the search
So i then search for 'live speed' expecting the same results, on the contuary there completly different.
