• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"international des opposition\") OR (\"internationale de l'opposition\"))) OR (((\"internationale d'ete opposition\") OR (((\"internationale contre opposition\") OR (\"internationale politiek opposition\"))))))~".
• Removing quotes may allow a broader search: (((( international des opposition ) OR ( internationale de l'opposition ))) OR ((( internationale d'ete opposition ) OR ((( internationale contre opposition ) OR ( internationale politiek opposition ))))))~.
• Adding a wildcard symbol may retrieve word variants: (((("international des opposition") OR ("internationale de l'opposition"))) OR ((("internationale d'ete opposition") OR ((("internationale contre opposition") OR ("internationale politiek opposition"))))))*.
