The Matched Records Sorting Components field controls how DSP orders matched target records when multiple matches exist. It accepts semicolon-separated expressions, evaluated in ascending order by default.

Example:

IsPrimary__c; -$FIELDS_COUNT; -LastModifiedDate  

This sorts records first by the number of populated fields (DESC), and if equal, by LastModifiedDate (DESC). Prefixing an expression with a minus sign (-) indicates descending order.
