Perhaps you should try some spelling variations:
communication 1 » communication _, communication a, communication 3
sme development » trade development
technologies a » technologies _, technologies 4, technologies 2
a formulation » la formulation, _ formulation, 3 formulation
development l » development li, development 1, development law
l afrique » en afrique
3 does » 13 does, 2 does, 1 does
4 does » 2 does
1 sme » _ sme, 3 sme, 5 sme

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 formulation ((3 does) OR (4 does)) _ communication 1 sme development l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies a formulation ((3 does) OR (4 does)) _ communication 1 sme development l afrique.*.
