• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"national regional stadte\\") OR ((\\"nationalstaat OR \\"nationalenstaat) legionary stadte\\"))\"".
• Removing quotes may allow a broader search: (( national regional stadte ) OR (( nationalstaat OR nationalenstaat) legionary stadte )).
