For those who think English or decimal is the only way to browse the Internet, you have another thing coming.   What we see below is Google filtering based on a specific string representation, ie match on thisdecimal.  So when we speak a different decimal representation, we bypass their filtering and the backend application understands our request.

For instance: Google hacking credit card numbers
