Subject [jira] Commented: (LUCENE-1896) Modify confusing javadoc for queryNorm
Date Mon, 07 Sep 2009 21:56:57 GMT


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 ...
