Applying relevance ranking to rule results

You can order results in a rule by their relevance ranking score for a given query term.

In some cases, it is a good idea to apply relevance ranking to a rule's results.

For example, if a user performs a record search for Mondavi, the results in the Highly Rated rule can be ordered according to their relevance ranking score for the term Mondavi. In order to create this effect, there are three requirements:

The navigation query that is triggering the rule must contain record search parameters (Ntt and Ntk). Likewise, the zone that the rule is assigned to must be identified as Valid for search (Otherwise, the rule will not be triggered).
The rule's target must be marked to Augment Navigation State.
The rule must not have any sort parameters specified. If the rule has an explicit sort parameter, that parameter overrides relevance ranking. Sort parameters for a rule are set on the General tab of the Rule editor.

If these three requirements are met, then the relevance ranking rules specified with MDEX Engine startup options are used to rank specific business rules when triggered with a record search request (a keyword trigger).
