Subject [jira] Created: (LUCENE-1534) idf(t) is not actually squared during scoring?

idf(t) is not actually squared during scoring?

                 Key: LUCENE-1534
             Project: Lucene - Java
          Issue Type: Bug
          Components: Query/Scoring
    Affects Versions: 2.4, 2.3.2, 2.3.1, 2.3, 2.2, 2.1
            Reporter: Michael McCandless
            Assignee: Michael McCandless
            Priority: Minor
             Fix For: 2.9

The javadocs for Similarity:

show idf(t) as being squared when computing net query score.  But I
don't think it is actually squared, in looking at the sources?  Maybe
it used to be, eg this interesting discussion:

Or am I missing something?  We just need to fix the javadocs to take
away the "squared"...
