Perhaps you should try some spelling variations:
4 communication » 3 communication, 5.4 communication, de communication
technologies 2 » technologies _, technologies 4
information a » information age, information about
development l » development li, development 1, development law
l afrique » en afrique
4 test » f test, 4.1 test
2 test » 3.2 test
e 4 » eu 4

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 2 information a e 4 communication ((4 test) OR (2 test)) development l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 information a e 4 communication ((4 test) OR (2 test)) development l afrique.*.
