The Nrcs parameter sets the list of stratified dimension values for use during refinement ranking by the MDEX Engine.

The Nrcs parameter groups specified dimension values into strata. The stratified dimension values specified in the parameter are delimited by semi-colons (;) and each stratified dimension value is in the format:


where dimvalID is the ID of the dimension value and stratumInt is a signed integer that signifies the stratum into which the dimension value will be placed.

The Nrcs parameter thus provides a mapping of dimension values to strata in the query:

You can define as many strata as you wish, but keep the following in mind:

Note that a dimension value will be stratified in the highest strata it matches, so boosting will have priority over burying.
