• The words AND, OR and NOT may confuse the search; try adding quotes: "typologie does variation did ((so 4) OR (soe 4)) communication 5 leur developpement et afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie does variation did ((so 4) OR (soe 4)) communication 5 leur developpement et afrique.*.
