public abstract class SortedDocValues extends BinaryDocValues
Per-Document values in a SortedDocValues are deduplicated, dereferenced, and sorted into a dictionary of unique values. A pointer to the dictionary value (ordinal) can be retrieved for each document. Ordinals are dense and in increasing sorted order.
