Hi mike, Thanks for the clarification. Any example about difference in using flat vs hierarchical facets? Any demo or sample page?
In a previous thread yesterday ( Faceting: Taxonomy index Vs SortedSetDocValues ), there is a point like "tried to achieve multilevel (hierarchical) categorization using SortedSetDocValues and got it simply by changing the query and opening the IndexReader for each level of query using SortedSetDocValuesReaderState.
