Perhaps you should try some spelling variations:
technologies co » technologies _, technologies 4, technologies 2
communication r » communication 3, communication 1, communication 2
d developpement » de developpement, du developpement, le developpement
developpement l » developpement il, developpement la, developpement de
co variation » how variation, _ variation, 2 variation
l afrique » en afrique
5d data » 3d data, id data, und data
d data » 3d data, id data, 1 data

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 co variation _ ((d data) OR (5d data)) communication r d developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies co variation _ ((d data) OR (5d data)) communication r d developpement l afrique.*.
