Perhaps you should try some spelling variations:
less developpement » le developpement, less development, leur developpement
developpement la » developpement de, developpement et, developpement du
information als » information age, information a, information act
la afrique » l afrique, la fabrique, en afrique
a less » _ less, a lens, a lesson
b 1.4 » _ 1.4, b 1.1, b 1.2
b 14 » _ 14, b 4, 2 14

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 _ information als ((b 14) OR (b 1.4)) communication a less developpement la afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies _ information als ((b 14) OR (b 1.4)) communication a less developpement la afrique.*.
