• The words AND, OR and NOT may confuse the search; try adding quotes: "technologies 2 informationen ((zu do) OR (eu do)) 14 communication a ou developpement de afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 informationen ((zu do) OR (eu do)) 14 communication a ou developpement de afrique.*.
