Extreme Googling

[Stelios Tigkas <kuffya () gmail com>]

Hi, 
Has anyone figured out how to search for special characters (in particular punctuation) in google? It seems that many 
critical characters such as [](),.@ are ignored by design in many of the main search engines. I've been testing it in a 
large variety of search engines but none worked as I'd like them to. This would be good-to-know for open source 
research, e-mail harvesting etc. 

Thanks, 
Stelios.
