Perhaps you should try some spelling variations:
developpement de » developpement des, developpement durable
le developpement » de developpement, sme development
technologies 1 » technologies _, technologies 4, technologies 2
de afrique » de l'afrique, en afrique, l afrique
1 wie » 1 die, 3 wie, 4 wie
2 wie » 2 die, 3 wie
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 1 information ((1 wie) OR (2 wie)) mass communication a le developpement de afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 1 information ((1 wie) OR (2 wie)) mass communication a le developpement de afrique.*.
