Perhaps you should try some spelling variations:
les developpement » le developpement, des developpements, leur developpement
communication 1 » communication _, communication a, communication 3
technologies 2 » technologies _, technologies 4
2 formation » 1 formation, 1.2 formation, 2 formulation
des afrique » en afrique, de l'afrique
et does » der does, act does, txt does
1 les » 2 les

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 2 formation ((et does) OR (et des)) _ communication 1 les developpement des afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 formation ((et does) OR (et des)) _ communication 1 les developpement des afrique.*.
