class  Lucene.Net.Index.SnapshotDeletionPolicy
 A IndexDeletionPolicy that wraps around any other IndexDeletionPolicy and adds the ability to hold and later release a single "snapshot" of an index. While the snapshot is held, the IndexWriter will not remove any files associated with it even if the index is otherwise being actively, arbitrarily changed. Because we wrap another arbitrary IndexDeletionPolicy, this gives you the freedom to continue using whatever IndexDeletionPolicy you would normally want to use with your index. Note that you can re-use a single instance of SnapshotDeletionPolicy across multiple writers as long as they are against the same index Directory. Any snapshot held when a writer is closed will "survive" when the next writer is opened. More...
