Fix Solr Facet Filters
Changes for commit: 486bfceb that remove non-faculty from the Faculty page break multi-word facet filters.
The syntax used in the base solr client relies on the removed escaping of spaces and other characters to send accurate filter queries.
The temporay fix will be to revert this commit and deploy.
Full fix will replace use of the paren and escape based method of building the fitlter queries with double quotes instead.
