Hi Shai, Yes, Splitting ranges into smaller ranges is not as same as sampling. I have used the wrong word there. I think RandomSamplingFacetsCollector is for "sampling" a larger dataset and that class cannot be used to implement the described example above. I think I ll have to prepare the Ranges manually and pass them to LongRangeFacetsCounts.
