• The words AND, OR and NOT may confuse the search; try adding quotes: "technology 4.2 inflation e ((case 13) OR (case 1)) communication et 2 development l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technology 4.2 inflation e ((case 13) OR (case 1)) communication et 2 development l afrique.*.
