A dropdown has been added to the facet configuration, listing all available facet query parameters from the query template. You can select a parameter from the list to explicitly link the facet to that query parameter. As a result, you can avoid hidden mismatches and make the configuration easier to understand and debug.
The following example shows the Facet search field checkbox selected for using the facet search counts from the connected facet data source for this filter field. The new Facet query parameter field with its dropdown list is displayed with its default value – the value of the Technical Name field above.
