Perhaps you should try some spelling variations:
die developpement » de developpement, le developpement, du developpement
developpement et » developpement des, developpement de, development east
information 1.2 » information 1.5.2, information 2
communication 2 » communication _, communication a, communication 3
technologies 2 » technologies _, technologies 4
et afrique » en afrique, l afrique
e 14 » e 1, 2 14, 3 14
_ 14 » _ 1, _ 4, _ 10

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 2 information 1.2 ((e 14) OR (_ 14)) communication 2 die developpement et afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 information 1.2 ((e 14) OR (_ 14)) communication 2 die developpement et afrique.*.
