Thanks for the note, Sergei. I admit to being confused by the documentation on boolean search. In particular, exactly what the problem domain for the two algorithms is supposed to be (and how relevancy is computed with boolean search). I don't understand why boolean search has (it seems) a totally different approach to relevancy.
Or to ask it a different way, which applications would use non-boolean search, and why? Also my understanding from the documentation and release notes is that boolean search is only available in 4.0.1, which is not yet available. Is this correct?
