I have often wondered this, but people tend to look at me like an idiot when I ask:

How do I Google "(^o^)v"?

Google counts the brackets as operators, so how do I get round this?

Google search ignores punctuation characters like these. Why would you need to search for that?

I found another search engine that can search it, but the results seem awfully limited: http://www.symbolhound.com/
