• The words AND, OR and NOT may confuse the search; try adding quotes: "technologies _ formacion ((de does) OR (do does)) cat communication r d developpement de afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies _ formacion ((de does) OR (do does)) cat communication r d developpement de afrique.*.
