Yes. Its much faster. The deletes are buffered and an IndexReader is
only opened to flush a specified number of buffered deletes.
IndexModifier is terribly inefficient and I think, to be deprecated soon.

Hello everyone,
I noticed that when updating a large index with IndexModifier
(lots of delete+add), the bottlenek was the delete. If I only add,
speed is at least multiplied by 50.
From what i have understood, its because a new IndexReader is
initialized for each delete.
Is the new updateDocument() method from IndexWriter optimized for
this kind of problem?
Thanks!
