StatsComponents stats.facet parameter doesn't support SimpleFacetParameters params like facet.mincount, facet.limit, etc. Moreover it'll always create Field Value Facets. Range Facets aren't possible.
Very useful to calculate the sum of a field for each month/day/etc (using range facets) or to limit the results with facet.limit.
New users interested in mixing stats & facets are encouraged to ignore the stats.facet param and instead combine
stats.field with facet.pivot to achieve similar results more efficiently...
