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