> NumericLeafComparator must have a method getPointValues similar how it has getNumericDocValues.
> Numeric Sort optimization with points relies on the assumption that points and doc values record the same information, as we substitute iterator over doc_values with one over points.
> If we extend {{getNumericDocValues}} it almost certainly means that whatever {{PointValues}} NumericComparator is going to look at shouldn't be used to skip non-competitive documents. Returning null for pointValues in this case will force comparator NOT to use sort optimization with points, and continue with a traditional way of iterating over doc values.
