• The words AND, OR and NOT may confuse the search; try adding quotes: "technologies fairs information a de 1 communication ((a net) OR (a new)) developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies fairs information a de 1 communication ((a net) OR (a new)) developpement en afrique.*.
