 * Run System on (Prod.) Server

+  sub-domain of the main site (Ritherdon Archive) for the Meilisearch

   This section builds on the one above (running on local machine). The main

+** Set-up Filter Attributes for Meilisearch Instance
+
+   After the search and main site's are set-up, you should be ready to set the
+   filter attributes used by Meilisearch. The quickest way to do that is to run
+   the following commands in SBCL (~rlwrap sbcl~),
+
+   #+begin_src common-lisp
+     (ql:quickload :ritherdon-archive)
+     (search:set-filter-attributes)
+     (exit)
+   #+end_src
+
+   You might need to stop the ritherdon-archive Systemd service ~sudo systemctl
+   stop ritherdon-archive.service~ to run the above commands. If that is the
+   case, remember to start the Systemd service, ~sudo systemctl start
+   ritherdon-achive.service~.
