Review comment:
> I think if a single document contains the same numeric value more than
once, indexed as a SortedNumericDocValuesField, Lucene will indeed index that
number multiple times for that document, and then this facet counting
implementation will count it multiple times for that one value, right?
Correct @mikemccand . I thought that this PR was for fixing that bug. I have
replicated that bug
[here](https://github.com/gautamworah96/lucene/commit/042878117308f76629a27b0bcf83e25f074dc8b1)
(see testLongValues)
So essentially, within a FacetResult you would want the `value` count for
the `label` to be counted just once but that is not the case today
I'll create a JIRA for it
