+The format for `solrFacets` is `"field_name" : "display title"`, notice that you can force the order of the facets by prefixing the display value with a number (e.g. "1|Subjects").
+
 * `serverAddress` is the address at which SolrDora will run on your local box. Do not prepend "http" to this setting.
 * `solrCoreUrl` is the URL of the Solr core that you want to connect to.
 * `solrOptions` is a set of options that will be passed to Solr on every request. In the previous example you can see how we set the default parser (defType) to "edismax" and defining the query field (qf) to use the author and title fields. Any valid Solr parameter can be configured here.
