Perhaps you should try some spelling variations:
developpement en » developpement et, developpement des, developpement de
technologies 4 » technologies _
4 information » 2 information, 1 information
information 1 » information 2, information 3, information 3.2
die mass » die masse, die mais, die massen
1 die » 2 die, 3 die, _ die
1 aug » 1 agg, 4 aug
1 auf » i auf, a auf, b auf

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 die mass communication ((1 aug) OR (1 auf)) developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 4 information 1 die mass communication ((1 aug) OR (1 auf)) developpement en afrique.*.
