 You have at least one solr field you want to display as a range limit, that's why you've installed this plugin. In your CatalogController, the facet configuration should look like:
 
 ```ruby
-config.add_facet_field 'pub_date', label: 'Publication Year', **default_range_config
+config.add_facet_field 'pub_date', label: 'Publication Year', range: true
 ```
 
 You should now get range limit display. More complicated configuration is available if desired, see Range Facet Configuration below.
