• The words AND, OR and NOT may confuse the search; try adding quotes: "typologie de variation ((3 der) OR (2 der)) 1 communication 4 does developpement des afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie de variation ((3 der) OR (2 der)) 1 communication 4 does developpement des afrique.*.
