Actually, refCount of a new IndexReader starts at 1. Then the caller must call close (which under the hood calls decRef) to drop it to 0. > @Question4: It seems to me that based on you explanation so far, the > IndexReader will end up closing after the very 1st search.

Actually, no -- SearcherManager also holds a ref. So when there are no queries in flight, the refCount will be 1. It's only when the searcher is swapped out for a new one that we decRef the old one and its refCount drops to 0 (once all in-flight queries finish). > I hope I haven't hijacked my own thread?
