+This signal will be called whenever a free-text order search is performed. You are expected to return one
+Q object that will be OR-ed with existing search queries. As order search exists on a global level as well,
+this is not an Event signal and will be called even if your plugin is not active. ``sender`` will contain the
+event if the search is performed within an event, and ``None`` otherwise. The search query will be passed as
+``query``.
