public class MultiDocValues extends Object
NOTE: for multi readers, you'll get better
performance by gathering the sub readers using
IndexReader.getContext()
to get the
atomic leaves and then operate per-LeafReader,
instead of using this class.
NOTE: This is very costly.

getNormValues(IndexReader r,
String field)
Returns a NumericDocValues for a reader's norms (potentially merging on-the-fly).

This is a slow way to access normalization values. Instead, access them per-segment
with LeafReader.getNormValues(String)
