Lucene does not allow queries to have negative scores. This can be problematic if you have a raw feature that has a negative value. Unfortunately there is no easy quick fix for this. If you are working with such features, you need to make them non-negative BEFORE you train your model. This can be accomplished by creating normalized fields with values shifted by the mininum value or you can run the score thru a function that produces a value >= 0.
