Thanks for your reply > The fastest way to do this is in fact to use a GenericUserBasedRecommender -- not because you need recommendations, but because it exposes a nice mostSimlarUsers() method.
Yes, that's the approach I was using. I was using almost the same code but with GenericUserBasedRecommender instead of the Boolean version, so thanks for the tip ;) > First, Lucene itself has related-search functionality. I have tried to look at it before, but I have only found the MoreLikeThis functionality, which is useful to obtain more similar *results*, I think.
