You may be able to get more results by adjusting your search query.

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