Given an IndexReader a custom filter is supposed to create a bit set, that maps each document numbers to {'visible', 'invisible'} On the other hand, it is stated that Lucene is allowed to change document numbers. Is it guaranteed that this BitSet's view of document numbers won't change while the BitSet is still in use (or perhaps the corresponding IndexReader is still opened) ?
And another (more low-level) question. When Lucene may change document numbers? Is it only when the index is optimized after there has been a delete operation?
