-----------------------------------------

             Summary: json.facet subfacet 'sort:"index asc", refine:true' can return diff results using method:enum
                 Key: SOLR-14595
                 URL: https://issues.apache.org/jira/browse/SOLR-14595
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
          Components: Facet Module
            Reporter: Chris M. Hostetter
            Assignee: Chris M. Hostetter


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...
