Perhaps you should try some spelling variations:
de communication » mobile communication, online communication
ides development » ads development, does development, smes development
does variation » de variation, der variation, die variation
typology does » typologie des, apology do's, typology how
1 afrique » l afrique, en afrique, 1 enrique
des dc » des do, des ducs

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: "typology does variation ((des dc) OR (des dr)) de communication _ ides development 1 afrique.~".
• Adding a wildcard symbol may retrieve word variants: typology does variation ((des dc) OR (des dr)) de communication _ ides development 1 afrique.*.
