What is the difference between afterDistinct and facetingAfterDistinct?

  • Updated
  • afterDistinct computes the facet counts of a specific attribute after distinct has been applied.  This only affects a single attribute. 
  • facetingAfterDistinct affects all attributes and it's applied to all facets of the query.
  • facetingAfterDistinct can only be set at query time. You can’t add it as a default setting of the index, while afterDistinct can be set in your attributesForFaceting
  • afterDistinct should only be used on attributes that are shared between all records with a common distinct key. Using it on attributes that have different values within a distinct group will lead to missing facet values & inconsistent facet counts.
  • Only use facetingAfterDistinct=true if all the facets queried fit the afterDistinct criterion of shared facet values within each group.
  • It may be advisable to hide facet counts of facets not using afterDistinct to avoid inconsistent counts across facets (some counting groups & others counting individual records)
