Hi,
The PriorityQueue used in TopDocCollector does not optimize the memory usage.
If I do this search:
TopDocs topDocs = searcher.search(query, null, 10000);
And only 1 document is returned. The PriorityQueue will create an Object[] of
size 10000 + 1, but only one position of the array is used.
The Lucene could implement a PriorityQueue with size extensible.
The PriorityQueue of the Sun is size extensible. Why does not use it?
Thanks
