Perhaps you should try some spelling variations:

3 communication » 4 communication, de communication, data communication
developpement l » developpement il, developpement la, developpement de
technologies 4 » technologies _
4 formulation » _ formulation, 3 formulation, 2 formulation
l afrique » en afrique
over do » ever do, over die
a le » a les, a la, a l

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 4 formulation ((over do) OR (over de)) 3 communication a le developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 4 formulation ((over do) OR (over de)) 3 communication a le developpement l afrique.*.
