For each dimension that has been enabled to return refinement counts, the MDEX Engine returns refinement counts for records that match descriptors. Descriptors are selected dimension values in this navigation state.

The refinement counts that the dgraph returns for descriptors are returned with the DGraph.Bins or DGraph.AggrBins property on the descriptor DimVal object returned through the Oracle Commerce navigation API.

The count represents the number of records (or aggregate records, in the case of DGraph.AggrBins) that match this dimension value in the current navigation state.

This capability of retrieving refinement counts for descriptors is the default behavior of the MDEX Engine. No additional configuration (for example, dgraph command line options) is needed to enable this capability.

To access the refinement counts for descriptors:
