Description

jenkins found a failing seed for TestCloudJSONFacetSKGEquiv that has nothing to do with SKG – it shows that using method:enum can sometimes return different set of buckets then method:smart when computing a facet that uses "sort":"index asc", "refine":true as a subfacet of some other facet.

(In all the cases i've been able to trigger with more targetted testing, the "parent facet" needs to use a sort option that cause buckets to "sort worse" when more data is known about them – ie: "count asc" or SKG – but i haven't determined if that's actaully neccessary to trigger the fialure)

original jenkins failure...
