Basis of an intelligent search engine

Here is a diagram for supporting the basis of my ideas for building a search engine. It`s very general and nothing specific - created with Gliffy (create and share diagrams online).
So the main point at the moment seems to be that it doesn`t get the input only from users (and from the internet), but it should retrieve it from anywhere possible. In my opinion, that kind of solution would just fit in the near future.
