Either optimize() or expungeDeletes() will reclaim the disk space used
by deleted documents.
Also, over time, as segments that have marked deletions are merged,
the disk space is also reclaimed.

Hello,
Could someone please confirm that calling indexWriter.optimize() is
the only
way to clean out the deleted documents from the disk?
I understand that indexWriter.deleteDocuments() does not clean the
disk
space, and I tested that calling after indexWriter.flush() and
indexWriter.close() after indexWriter.deleteDocuments() does not
clean the
disk space either. So do they only mark the documents have been
deleted,
then which method really do the "delete" the documents (from the
disk)?
Thanks,
Dan
