4 developpement » de developpement, le developpement, et developpement
a communication » la communication, data communication, data communications
3 information » 1 information
technology 3 » technology _, technology 1, technology 4
il afrique » l afrique, en afrique
costs 4 » costs _, costs a, costs 4.2
3 does » 13 does, 2 does, 1 does
4 does » 2 does

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: "technology 3 information ((3 does) OR (4 does)) a communication costs 4 developpement il afrique.~".
• Adding a wildcard symbol may retrieve word variants: technology 3 information ((3 does) OR (4 does)) a communication costs 4 developpement il afrique.*.
