• The words AND, OR and NOT may confuse the search; try adding quotes: "typology die variation ((6 der) OR (2 der)) 4 communication a der developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: typology die variation ((6 der) OR (2 der)) 4 communication a der developpement en afrique.*.
