  Even though index searching is a read only operation, the !IndexSearcher must momentarily lock the index when it is opened in order to get the list of files in the index.  If locking is not configured properly it gets an incorrect list (because the list of files changes as the !IndexWriter adds docs or optimizes the index).  Remote filesystems (like NFS and Samba) rarely work, because they cannot make the transactional guarantees neccessary to ensure that all clients get consistent views of the directory.

- Does '''TopDocCollector''' continue to collecte documents even when hq is full?
+ Does '''TopDocCollector''' continue to collect documents even when hq is full?
  IF NOT, does it mean that the collect operation DO NOT cover all the documents?
  Pls refer to lucene-2.2.0-src
