Perhaps you should try some spelling variations:
variation series » education series, action series, edition series
de communication » mobile communication, online communication
typologie does » typologie des, typologie der, typologie cices
does variation » de variation, der variation, die variation
development l » development li, development 1, development law
l afrique » en afrique
8.4 smes » 8.3 smes, 8.4 smis, 8.4 smash
4 smes » _ smes, 8 smes

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: "typologie does variation series _ de communication ((4 smes) OR (8.4 smes)) development l afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie does variation series _ de communication ((4 smes) OR (8.4 smes)) development l afrique.*.
