• Removing quotes may allow a broader search: (((((((( internationale contre opposition ) OR ( internationale conferentie opposition ))) OR ( internationale des opposition ))) OR ( internationale politiek opposition ))) OR ( internationale de l'opposition ))~.
• Adding a wildcard symbol may retrieve word variants: (((((((("internationale contre opposition") OR ("internationale conferentie opposition"))) OR ("internationale des opposition"))) OR ("internationale politiek opposition"))) OR ("internationale de l'opposition"))*.
