• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"national regional state\\") OR ((\\"nationale OR \\"nationalenene) region (statt\\" OR stadt\\")))\"".
• Removing quotes may allow a broader search: (( national regional state ) OR (( nationale OR nationalenene) region (statt OR stadt ))).
