Hello All !
I see delete method in IndexReader, but when I delete item from
reader - this item will not be deleted physically.
So I must rewrite all index after each deleting ??
Or it is quite smart to be rewrited partially ?

You don't need to rewrite the index after each deletion,
but you could consider optimizing it after a batch of
changes. See the javadoc for IndexWriter.

I think if you call IndexReader.close() then the deleted item really goes away.
