Include only a list of specific values for facets.
Can be set in: collection.cfg
This option specifies a list of terms allowed to be displayed in faceted navigation values.
This option applies to all facets, see
for setting a white list for a specific facet.
The value is a comma separated list of terms. Only the term from this list will be displayed as values for the given facet. The matches are case-insensitive.
Because the list is comma-separated, whitelisting values that contain comma is not possible. To whitelist faceted navigation categories creating commas, a custom plugin is required.
