Currently, LongRangeFacetCounts and DoubleRangeFacetCounts do not support such capabilities when it comes to flat index structure. For nested structures, this could be simulated by disabling NestedProvider. Then it could work so that it would aggregate separate values from nested documents. But also you can make the new LongRangeFacetCounts and DoubleRangeFacetCounts so that it works according to our assumptions.
