• The words AND, OR and NOT may confuse the search; try adding quotes: "typologie de action series ((das mass) OR (das max)) communication a de developpement de afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie de action series ((das mass) OR (das max)) communication a de developpement de afrique.*.
