Perhaps you should try some spelling variations:
le developpement » de developpement, sme development
3 communication » 4 communication, de communication, data communication
communication 1 » communication _, communication a, communication 3
developpement l » developpement il, developpement la, developpement de
l afrique » en afrique
a does » 4 does, 1 does, 3 does
2 does » 4 does
1 le » 1 les, 1 la, 3 le

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 _ calculation ((a does) OR (2 does)) 3 communication 1 le developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies _ calculation ((a does) OR (2 does)) 3 communication 1 le developpement l afrique.*.
