Perhaps you should try some spelling variations:
trade development » software development
technologies 2 » technologies _, technologies 4
applications 3 » applications _
information 2 » information 3
development l » development li, development 1, development law
l afrique » en afrique
3 trade » 1 trade, 4 trade, 2 trade
cie 2 » c.e 2, cie _, civ 2
ci 2 » civ 2, ii 2, i 2

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 2 ((cie 2) OR (ci 2)) applications 3 trade development l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 information 2 ((cie 2) OR (ci 2)) applications 3 trade development l afrique.*.
