Perhaps you should try some spelling variations:
does developpement » de developpement, des developpements, does development
typologie does » typologie des, typologie der, typologie cices
does variation » de variation, der variation, die variation
variation 3 » variation _, variation 6, variation 5
des afrique » en afrique, de l'afrique
der 12 » der 10, der 11, der 15
a does » 2 does, 4 does, 1 does
der 1 » der 10, der 11, der 15

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 3 ((der 1) OR (der 12)) communication a does developpement des afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie does variation 3 ((der 1) OR (der 12)) communication a does developpement des afrique.*.
