[squid-users] Blocking Searches with squidguard

Is there any way I can configure squidguard 1.2.0 to block searches such as:

http://www.google.co.uk/search?q=boobs

and

http://www.google.co.uk/search?stuff=some+stuff&q=boobs&morestuff=more+stuff

Where boobs is any one of a selection of forbidden words?
