• The words AND, OR and NOT may confuse the search; try adding quotes: "technologies _ information ((pt e) OR (pt 2)) u.s communications put get developpement de afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies _ information ((pt e) OR (pt 2)) u.s communications put get developpement de afrique.*.
