The problem is that the current indexing (both ft and suggestion) is only based on word occurrence. Even if this works good there is no easy way for the index to know that the Wikipedia "Apple" is more important than ".apple".

The idea would be to be avaible to slightly tweak the current algorithm by giving an external numerical factor at indexing time. That way we could make a ponderation and effectively give better search results.

In the case of Wikipedia such a number could be for example computed (and is actually already computed) within the WP1 project.
