- make model.Notebook.sql_search_notes() search either with user_id or an anonymous user_id, not both - update controller.Notebooks.search(), so if the anonymous user has access to the given notebook, then run the search as the anonymous user instead of the given user id - update unit tests - don't search trash/deleted notebooks
