Type 45+12 into Google. What do you get? Well, you're just going
to see a listing of sites that contain that term. Wrong. Google is
smart enough to invoke its calculator when you type a mathematical
expression. So the result you get is 45+12=57. Neat.

Can't find something on a website but you're pretty sure it's somewhere
on it? Type the term you're looking for and follow it with site:thesite.com.
For instance, if you want to find out all the sites on this domain
that I mention my wife (please don't do this :-), type
marta site:kubasek.com.
I'm going to get killed...

Another cool thing is safesearch. Let's say you need to search for sex
education but you're not interested in all of the porn sites. Type
safesearch: sex education. This will filter out the adult sites from
your search.
