Perhaps you should try some spelling variations:
4 communication » 3 communication, 5.4 communication, de communication
developpement l » developpement il, developpement la, developpement de
technologies 3 » technologies _, technologies 4, technologies 2
3 informations » 3 information, 2 informations, 4 informations
l afrique » en afrique
und we » und wer, und web, und weg
_ ein » _ eine
we 4 » web 4, we _, e 4

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 informations und we 4 communication ((3 ein) OR (_ ein)) developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 3 informations und we 4 communication ((3 ein) OR (_ ein)) developpement l afrique.*.
