Perhaps you should try some spelling variations:
communication 3.3 » communication _, communication a, communication 1
10 communication » 1 communication, de communication, 3 communication
sme development » trade development
development l » development li, development 1, development law
l afrique » en afrique
after eu » after end, after _, after a
after e » after _, after a, after 2
3.3 sme » 3.3 some, 3.3 step, 3.3 stem

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 _ formation ((after e) OR (after eu)) 10 communication 3.3 sme development l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies _ formation ((after e) OR (after eu)) 10 communication 3.3 sme development l afrique.*.
