Perhaps you should try some spelling variations:
data communication » data communications
le developpement » de developpement, sme development
developpement l » developpement il, developpement la, developpement de
des variation » does variation, de variation, der variation
l afrique » en afrique
im does » m does, jam does
a le » a les, a la, a l
typologie » typologies, typology

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: "typologie des variation ((im does) OR (im doner)) data communication a le developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie des variation ((im does) OR (im doner)) data communication a le developpement l afrique.*.
