Two new features allow you to manipulate the rankings of returned records or dimension values.

Record boost and bury is a mechanism by which the ranking of certain specific records is made much higher or lower than other records. This allows you to manipulate ranking of results in order to push certain types of records to the top or bottom of the results list. The feature depends on the use of the new stratify relevance ranking module.

Dimension value boost and bury is a companion feature that allows you to re-order returned dimension values. With this feature, you can place dimension values into ranked strata, in order to promote or push down refinements. The feature depends on the use of the new Nrcs URL parameter and the related Presentation API methods.

See the MDEX Engine Development Guide for details on these features.
