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