public Bits getLiveDocs()
LeafReaderBits representing live (not
deleted) docs. A set bit indicates the doc ID has not
been deleted. If this method returns null it means
there are no deleted documents (all documents are
live).
The returned instance has been safely published for
use by multiple threads without additional
synchronization.getLiveDocs in class FilterLeafReaderpublic int numDocs()

LeafReaderIndexReader.CacheHelper that can be used to cache
based on the content of this leaf regardless of deletions. Two readers
that have the same data but different sets of deleted documents or doc
values updates may be considered equal. Consider using
IndexReader.getReaderCacheHelper() if you need deletions or dv updates to be
taken into account.
A return value of null indicates that this reader is not suited
for caching, which is typically the case for short-lived wrappers that
alter the content of the wrapped leaf reader.
