Perhaps you should try some spelling variations:
au developpement » du developpement, de developpement, le developpement
developpement l » developpement il, developpement la, developpement de
technologies 4 » technologies _
4 information » 2 information, 1 information
information 1 » information 2, information 3, information 3.2
l afrique » en afrique
ein mass » einer mass, air mass

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 4 information 1 ((ein mass) OR (ein mis)) communication _ au developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 4 information 1 ((ein mass) OR (ein mis)) communication _ au developpement l afrique.*.
