• The words AND, OR and NOT may confuse the search; try adding quotes: "technologies 4 formation _ ((how 4) OR (how 24)) communications av et developpement de l'afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 4 formation _ ((how 4) OR (how 24)) communications av et developpement de l'afrique.*.
