+            the advanced filters used in Plex Web with a tree of ``and``/``or`` branches. Each level of the tree must
+            start with ``and`` (Match all of the following) or ``or`` (Match any of the following) as the dictionary
+            key, and a list of dictionaries with the desired filters as the dictionary value.
+
+            The following example matches `this <../_static/images/LibrarySection.search_filters.png>`__ advanced filter
+            in Plex Web.
