All segments are disk segments. However, the buffered delete terms are
applied differently: for the segment just flushed from ram, delete
terms are applied appropriately so that a delete term is only applied
to the documents buffered before it, not those buffered after it;
delete terms are applied to all the documents in all other segments.
