public IndexReader.CacheHelper getCoreCacheHelper()
LeafReader
IndexReader.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.
