Perhaps you should try some spelling variations:

communication 1 » communication _, communication a, communication 3
developpement l » developpement il, developpement la, developpement de
information 3 » information 2
l afrique » en afrique
cge data » age data, wage data, care data
e data » e datas, age data, mwe data
1 au » 1 auf, 1 aug, 1 a

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 _ information 3 ((e data) OR (cge data)) communication 1 au developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies _ information 3 ((e data) OR (cge data)) communication 1 au developpement l afrique.*.
