• The words AND, OR and NOT may confuse the search; try adding quotes: "technologies 1 information 3 3 2 communication ((a du) OR (a de)) developpement la afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 1 information 3 3 2 communication ((a du) OR (a de)) developpement la afrique.*.
