Perhaps you should try some spelling variations:
developpement de » developpement des, developpement durable
typologie de » typologie des, typologie der, typologien der
de variation » der variation, die variation, does variation
im business » 3 business, 2 business, 4 business
a du » a d, a de, _ du
a u » a un, a us

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 de variation _ im business community ((a du) OR (a u)) developpement de l'afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie de variation _ im business community ((a du) OR (a u)) developpement de l'afrique.*.
