Perhaps you should try some spelling variations:
le developpement » de developpement, sme development
developpement et » developpement des, developpement de, development east
4 communication » 3 communication, 5.4 communication, de communication
technologies 3 » technologies _, technologies 4, technologies 2
3 formulation » _ formulation, _ formulating
et afrique » en afrique, l 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 3 formulation ((over do) OR (over de)) 4 communication a le developpement et afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 3 formulation ((over do) OR (over de)) 4 communication a le developpement et afrique.*.
