Perhaps you should try some spelling variations:
du developpement » de developpement, le developpement, et developpement
developpement et » developpement des, developpement de, development east
e communication » de communication, 1 communication, une communication
technologies 2 » technologies _, technologies 4
et afrique » en afrique, l afrique
banks e » banks 1, banks a, banks 3
a du » a d, a de, a u

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