Mark Miller commented on LUCENE-1896:
-------------------------------------
Hmm .. so perhaps the idea that they query scores are more comparable comes
from:
if we take it out, that means the score will be the cosine X the euclidean
distance - the distance will be rather large for a small query vector and a
large doc vector (in magnitude). So a query that matched many large docs would
could scale a lot harder than a query that hit small docs?
I guess that makes sense - scores not being very comparable anyway though, it
hardly seems worth the extra compute cost ...
