I've been stepping through the contrib MoreLikeThis class and was wondering if people can give opinions on why you would or would not use setBoost(true) for the MoreLikeThis object. It seems a bit odd (at least to me) to boost the "good" terms in the query (based on the term's score), since won't the final score (once you use the query) in some sense "reflect" the effect of good terms already through the tf-idf? Is using boost in some way trying to "make up" for the fact that the returned query for the MLT object "loses" the term frequency of the terms in the reference document (that is, no matter how many times a term is in the reference document, the query remains the same, assuming that the term makes it into the query via the MLT heuristics).
Thanks for any words of wisdom-- Donna
