Perhaps you should try some spelling variations:
et developpement » de developpement, le developpement, test development
developpement en » developpement et, developpement des, developpement de
formation where » formulation where, formation when, formation over
technologies a » technologies _, technologies 4, technologies 2
a formation » la formation, 1 formation, a formulation
a et » a set, a net, a bet

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 a formation where ((do i) OR (do _)) communication a et developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies a formation where ((do i) OR (do _)) communication a et developpement en afrique.*.
