Perhaps you should try some spelling variations:
et developpement » de developpement, le developpement, test development
communication 4 » communication _, communication a, communication 3
developpement l » developpement il, developpement la, developpement de
technologies 2 » technologies _, technologies 4
information a » information age, information about
l afrique » en afrique
eu 4 » eu _, eu a, eu 1
4 et » 4 get, 4 set, 4 el

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 2 information a ((e 4) OR (eu 4)) communication 4 et developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 information a ((e 4) OR (eu 4)) communication 4 et developpement l afrique.*.
