> Lucene appears to be inconsistent on this behaviour; the FSDirectory documents a FileNotfoundException but actually returns 0 while the RAMDirectory implements the FileNotfoundException but is totally synchronized,
> I assume the FSDirectory is more reliable in this case and we got a reported error about this, my rationale is that the race condition which FSDirectory can handle is never an issue in the synchronized blocks of RAMDirectory.
> Inspecting the code of Lucene, there appears to be no harm done in returning 0 for unexistend metadata.
