Perhaps you should try some spelling variations:
au developpement » du developpement, de developpement, le developpement
developpement en » developpement et, developpement des, developpement de
3 applications » 3 application
technologies 2 » technologies _, technologies 4
3 le » 3 les, 3 la, 1 le
3 e » 3 el

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: technologies 2 information ((3 e) OR (3 le)) 3 applications _ au developpement en afrique.~.
• Adding a wildcard symbol may retrieve word variants: technologies 2 information ((3 e) or (3 le)) 3 applications _ au developpement en afrique.*.
