Subject Faceting : what are the limitations of Taxonomy (Separate index and hierarchical facets) and SortedSetDocValuesFacetField ( flat facets and no sidecar index) ?
Date Thu, 10 Nov 2016 10:30:56 GMT
Hi All,
            We all know that Lucene supports faceting by providing
Taxonomy(Separate index and hierarchical facets) and
SortedSetDocValuesFacetField ( flat facets and no sidecar index).

      Then why did solr and elastic search go for its own implementation ?
 ( that is, solr uses block join & elasticsearch uses aggregations ) Is
there any limitations in lucene's implementation ?
