I am not sure for 100%, but I guess that i have "no index" for many pages like the profiles, search and other non relevant things.
The question is now: What is indexed? 35T+236T from the pages to index or from all existing pages?
And then: How can a site have such numbers with maybe 10.000 threads and 10.000 resources?
This makes never ever 35T pages. So why Google is talking about 236.000 pages not indexed?
