A Boolean function is a function that has n variables or entries, so it has 2n possible combinations of the variables. These functions will assume only 0 or 1 in its output. An example of a Boolean function is this, f(a,b,c) = a X b + c. These functions are implemented with the logic gates.

## Do Boolean searches work on Google?

Boolean methods can be used on any search engine: Google, LinkedIn, or even Facebook.
