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