Perhaps you should try some spelling variations:
zur developpement » leur developpement, du developpement, au developpement
developpement il » developpement de, developpement et, developpement du
technologies 4 » technologies _
4 information » 2 information, 1 information
il afrique » l afrique, en afrique
1 aid » _ aid, 1 aim, 1 air
1 add » _ add
a zur » 1 zur, 2 zur, 3 zur

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 aid) OR (1 add)) mass communication a zur developpement il afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 4 information ((1 aid) OR (1 add)) mass communication a zur developpement il afrique.*.
