Short answer: you can't.
1. No Google does not allow you to use regular expressions.
2. To search the Internet you would have to read every page that exists everywhere. A conservative estimate is over a petabyte of data -- a thousand million megabytes -- and it might be 50 times that. If your broadband connection can read a megabyte a second, it would still take at least 31 years and probably annoy your ISP.
