> MultiSearcher.search places sorted search results from individual searchers into a PriorityQueue.  This can be made to be more optimal by taking advantage of the fact that the results returned are already sorted.  
> The proposed solution places the sub-searcher results iterator into a custom PriorityQueue that produces the sorted ScoreDocs.
