Do you think that the similar users approach of Lucene is similar to the "most similar users" of mahout?

I like Taste's mostSimilarUsers(), but I wish it exposed/returned the similarity metric, so one can use this method and see exactly how similar those most similar users are. For example, an application may want to show or hide similar users based on this similarity "distance" from the given user. Otis -- Sematext -- http://sematext.com/ -- Lucene - Solr - Nutch
