• The words AND, OR and NOT may confuse the search; try adding quotes: "technologies b informations ((und e) OR (und 3)) 3 communication 3.3 data developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies b informations ((und e) OR (und 3)) 3 communication 3.3 data developpement l afrique.*.
