Thanks for sharing Adrien, this is really cool! It's neat that the relative gains of Java vs C are quite a bit less than they were ~11 years ago when I played with a much smaller subset of queries. Also, COUNT on disjunction queries with Lucene Cyborg got slower. What a feat, to port so much of our complex Search code to C!
