Perhaps you should try some spelling variations:
developpement la » developpement de, developpement et, developpement du
2 communication » 3 communication, 4 communication, 1 communication
technologies a » technologies _, technologies 4, technologies 2
a informations » a information, 2 informations, 3 informations
la afrique » l afrique, la fabrique, en afrique
3.4 et » 3.4 el
3.4 eq » 3.4 el
und e » und _, und 2, und 3

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 informations und e 2 communication ((3.4 et) OR (3.4 eq)) developpement la afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies a informations und e 2 communication ((3.4 et) OR (3.4 eq)) developpement la afrique.*.
