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