+\r
+The search command executes a new global search. It will display all\r
+threads from the database with messages that match the search terms.\r
+\r
+The filter command refines the current search. It will take the current\r
+search and filter it down to those threads with messages match the\r
+search terms.\r
+\r
+The filter command is a convenience function for taking the current\r
+search terms, appending "and <new-search-terms>" and then running a new\r
+global search.\r
+\r
+Does that make sense?\r
