:-) The Limits of The Internet

I noticed something quite peculiar today. When you search for a smiley face :-) no results are returned on google or on bing? The face smile is one of the most used smileys on cellphones and emails how can there be no posts about it on the internet? How weird. I will now end this observation with a few smileys with the hope that the google bots might catch it soon :) :-) :') X-) :P :D
