Hm, Erik is not alone with unit tests failing. My HighlighterTest
passes (I didn't do svn update today yet), but I see SortTest failing:

Line 365 is this:
assertSameValues (scoresA, getScores(multi.search(queryA,sort)));
And this makes me think that this broke during my last commit of Wolf's
patch for MultiSearcher and docFreq stuff. However I did run 'ant
test' before commit and did see BUILD SUCCESSFUL, so I'm not 100% sure.
Anyone else seeing this error?
Otis, I think that is a bug in the test case that Wolf's patch has
exposed. It creates an index consisting of two copies of "full". This
should be equivalent to an index where every document is duplicated
(occurs twice), not to an index where each document occurs only once.
With the new correct idf normalizaiton, this increases all the docfreq's
for the terms, which changes the score. Scores on the duplicated index
should not be the same as scores on the unduplicated index.
