• The words AND, OR and NOT may confuse the search; try adding quotes: "technologies _ information port du laos communications ((a l) OR (a la)) developpement du afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies _ information port du laos communications ((a l) OR (a la)) developpement du afrique.*.
