There are all kinds of games you can play with Google, including the well-known 'Googlewhacking'. I don't know whether I've invented this one, which I discovered accidentally.
It is very simple: just hit a few keys haphazardly, for example, "l;kd" in the search box of Yahoo and see what turns up. The aim is to put in something that returns nothing - which is surprisingly difficult! That combination, for example, turned up more than one and half million hits! Even entered as a phrase, it produced almost 20,000.
The string ";we[kear'k" resulted in 34 hits, largely as a result of the existence of an author called "K. Kear". However, as a phrase, it produced zero - so it can be done. Remember, however, that they entry of symbols should be haphazard, just let your fingers do the choosing.
