But with automagic query expansion these things might be done behind
the scenes. Nutch, for one, expands simple queries to check against

Does anyone knows if it is possible or if such an evolution is under

I suppose you mean search within search, so that the second search is
SearchBean should be discussed on this list - no need to contact the
original developer directly (in fact, it's a better practice to discuss
open source code in the appropriate public forums).

Without looking at your code, a good first suggestion is to se
IndexSearcher.explain(Query,docId) to see why scores are they way they
are.

Erik,
Could you expand on this just a wee bit, perhaps with an example of
how to
compute this vector angle?
I'm tempted to write the code to see how it works, but FYI this doc
seems to nicely explain the concepts:

What about using term vectors though? I've been able to do rudimentary
