Exclude specific values for a specific facet.
Can be set in: collection.cfg
This option specifies a list of terms that should be removed from faceted navigation values.
This parameter is suffixed with the facet name to apply the black list to. The format is:
The value is a comma separated list of terms. Those terms will be removed from the values for the given facet. The matches are case-insensitive.
Prevent "Sydney" and "Melbourne" from appearing only on the "Location" facet:
Because the list is comma-separated, blacklisting values that contain comma is not possible. To blacklist faceted navigation categories creating commas, a custom plugin is required.
