The MDEX Engine uses the aggregated record counts beneath a given refinement for its refinement ranking strategy only if they were computed for the query sent to the MDEX Engine.

The MDEX Engine computes refinement ranking based on statistics for the number of records beneath a given refinement. In the case of aggregated records, refinement ranking depends on whether you have requested the MDEX Engine to compute statistics for aggregated record counts beneath a given refinement.

The following statements describe the behavior:

To summarize, the MDEX Engine uses the aggregated record counts beneath a given refinement for its refinement ranking strategy only if they were computed. In all other cases, it uses only regular record counts for refinement ranking.
