• Removing quotes may allow a broader search: (((( national regional state ) OR ( nationaleren regional state ))) OR ( national region state ))~.
• Adding a wildcard symbol may retrieve word variants: (((("national regional state") OR ("nationaleren regional state"))) OR ("national region state"))*.
