public class BlockTermsReader extends FieldsProducer
PostingsReaderBase
. This class is reusable for
codecs that use a different format for
docs/freqs/positions (though codecs are also free to
make their own terms dict impl).
This class also interacts with an instance of TermsIndexReaderBase
, to abstract away the specific
implementation of the terms dict index.
