It looks like it according to a featured thread at Search Engine Watch Forums named Sept. 2005 Google Index Update & Size Increase Coming?
In that thread, member shor reported huge increases in the indexing of some of a sampling of his clients.
Sample (5 sites): Datacenters: 184.108.40.206, 220.127.116.11, 18.104.22.168
Date 5/09/2005 17:11 1,870,000 1,730,000 349,000 544,000 317,000 7/09/2005 13:00 4,910,000 4,660,000 828,000 1,512,000 864,000
One of the convincing factors, as Danny notes in the thread and in his blog postings, linked to within the thread, is that when you do a search on "the" you get over 8 billion pages. At this moment in time, at 22.214.171.124 for the search the I get 8,640,000,000 results. The is pretty amazing, since Google is only "Searching 8,168,684,336 web pages." The is a difference of 471,315,664 pages, meaning Google indexed more pages for the keyword "the" then what is listed on the Google homepage footer.
