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