Geo Distance / Range Facets might count documents several times for a range entry if the field is multi valued

Issue: The Geo Distance facet reports the number of the matching locations, if a single document has two matching locations the facet count will be 2 instead of 1 (only one document). An option to only count the number of matching documents is desired to fully implement it as a navigation facet.

Note, this also applies to range facet.
