Nope. The counts for the scenario you describe should add up exactly for single-valued fields. Are you sure you're adding in the "missing" bucket? When you some up the sub-facets on Type, do you get a value under or over the counts on the parent facet? Verify that Type is single-valued. One would not expect facets on a multi-valued field to add up in the same way. Verify that you're getting all of the Type constraints by using a limit of -1on that sub-facet. -Yonik
