et developpement » de developpement, le developpement, test development
developpement de » developpement des, developpement durable
4 informationen » _ informationen, b informationen, av informationen

• The words AND, OR and NOT may confuse the search; try adding quotes: "technologies 4 informationen zur ((co 2) OR (c 2)) communications _ et developpement de afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 4 informationen zur ((co 2) OR (c 2)) communications _ et developpement de afrique.*.
