Perhaps you should try some spelling variations:
la communication » data communication, data communications
technologies a » technologies _, technologies 4, technologies 2
development co » development case, development china
a information » 2 information, 1 information
e development » sme development, mine development, site development
co afrique » en afrique, l afrique
needs de » needs men, needs one, needs _
needs a » needs _

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 a information ((needs de) OR (needs a)) la communication _ e development co afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies a information ((needs de) OR (needs a)) la communication _ e development co afrique.*.
