• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"national regional state\") OR (((\"national regionen state\") OR (\"nationale regionen state\"))))~".
• Removing quotes may allow a broader search: (( national regional state ) OR ((( national regionen state ) OR ( nationale regionen state ))))~.
• Adding a wildcard symbol may retrieve word variants: (("national regional state") OR ((("national regionen state") OR ("nationale regionen state"))))*.
