Not sure, but I'd guess something like 'www' would be near the top -- unless Google do something smart with that.

Looks like 'www' gets 'About 25,270,000,000 results', so there's a good starting point, or a good indicator of the limit of what Google will display.

Searching for 1 or 0 gives the same number of result. Probably this is the number of pages indexed by Google.
