• The words AND, OR and NOT may confuse the search; try adding quotes: "technology 2 inflation a price a communication ((a de) OR (a des)) developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: technology 2 inflation a price a communication ((a de) OR (a des)) developpement en afrique.*.
