I don't recall if this is common or not during the google dance but if you search for something in www and compare the number of results to www2 there is an astonishing jump up in the number of results.

Is showing Results 1 - 10 of about 96,100,000.

Was showing Results 1 - 10 of about 80,000,000.

Does this mean there will be 16 million more results for the keyword program in this next index?
