   Actually I don't think we need a growable priority queue. For such large number of hits it'd be probably more efficient to collect hits in an ArrayList first and only turn it into a PQ once there are `numHits` hits?
   
   Pinging @tokee since this is a topic he already spent time thinking about. :)
