Description

I believe TopUsers.getTopUsers() is not properly handling the rescoredSimilarity:

TopItems.getTopUsers:
double rescoredSimilarity = rescorer == null ? similarity : rescorer.rescore(userID, similarity);
      if (!Double.isNaN(rescoredSimilarity) && (!full || rescoredSimilarity > lowestTopValue)) {
        topUsers.add(new SimilarUser(userID, similarity));

It is checking rescoredSimilarity for everything, but then not passing it in like getTopItems does.
