Delete the index Directory in File System, I think this is the simpliest!!!

If you're on Windows, the safest way to do this in general, if there  
is any possibility that readers are still using the index, is to  
create a new IndexWriter with create=true.  Windows does not let you  
remove open files.  IndexWriter will gracefully handle failed deletes  
by retrying them over time...
