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