We can add an extra range that includes everything, + // or consider supporting overall count in CountFacetRecorder. But it is not exactly the value + // we can get now, as this value wouldn't respect top-n cutoff. Is this value a must have facets Review Comment: I was under impression that it has to be sum value only for docs from top N, I think I misread javadoc for `FacetResult#value`, it says "Total number of documents containing a value for this path, **even those not included in the topN**.". So we actually *can* implement computing the value, just need to change range facets and add a facet ordinal that means "some range from the list". At the same time I'd suggest that we do it as a follow up task, I think it's ok to not have full feature parity in the first release? If you're ok with it, I'll just update the comment and add a TODO item for now. -- This is an automated message from the Apache Git Service.
