Hi Pedro, Lucene's Explanation will show you all the juicy details: http://lucene.apache.org/java/2_4_1/api/core/org/apache/lucene/search/Scorer.html#explain(int)
But with a query like that, I'm not sure if you'll be able to follow everything. Maybe pick a super simple pair of queries instead, and look at Explanation for those simple queries to see what's happening and how they are being scored.
