Perhaps you should try some spelling variations:
developpement en » developpement et, developpement des, developpement de
4 communication » 3 communication, 5.4 communication, de communication
typologie der » typologie des, ideologie der
der variation » de variation, does variation, die variation
5 power » 2 power, 3 power
4 power » 2 power, 3 power
soe 4 » boe 4, ioe 4, sos 4

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 der variation _ soe 4 communication ((5 power) OR (4 power)) developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie der variation _ soe 4 communication ((5 power) OR (4 power)) developpement en afrique.*.
