+1 I think Lucene's current PQ is optimized for the [very] common case, and if someone would like to eg swap to Sun's PQ impl, the custom Collector API is the best route. (And, I'd love to hear back on how the performance compares! If Sun has a faster PQ than Lucene, we should fix that ;) ). Though, are Lucene's core collectors reusable? If you did really want say 100K results out of each search (very unusual), it'd be nice to not have to throw away the Collector/PQ each time.
