Class FieldComparer.TermOrdValComparer

Sorts by field's natural Term sort order, using ordinals. This is functionally equivalent to FieldComparer.TermValComparer, but it first resolves the string to their relative ordinal positions (using the index returned by GetTermsIndex(AtomicReader, String, Single)), and does most comparisons using the ordinals. For medium to large results, this comparer will be much faster than FieldComparer.TermValComparer. For very small result sets it may be slower.
