Google Finds 1 Trillion Unique URL’s

What they note way down in the fourth paragraph, however, is that they don’t actually index all of those pages, so you can’t find them on Google. Estimates on the true size of the Google index are a mere 40 billion pages or so.
Michael Arrington of TechCrunch had this to say about the timing of the announcement:
Why don’t they index all the pages they’ve found? Some of them are spam. But it’s also very expensive to index sites. And the fact that Google indexes many news sites, blogs and other rapidly changing web sites every 15 minutes makes all that indexing even more expensive. So they make value judgment on what to actually index and what not to. And most of the web is left out.
Google also says “But we’re proud to have the most comprehensive index of any search engine.”
That may be true today, but it probably won’t be true next week (check back here then). Google knows that as well as we do, and that’s why they posted this today.
