• The words AND, OR and NOT may confuse the search; try adding quotes: "technologies 2 information 2.2 der 3.2 communication ((a et) OR (a net)) developpement du afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 information 2.2 der 3.2 communication ((a et) OR (a net)) developpement du afrique.*.
