Perhaps you should try some spelling variations:
developpement en » developpement et, developpement des, developpement de
apologien der » typologien der, apologie des, ideologien der
der variation » de variation, does variation, die variation
our business » your business, der business, other business
a du » a d, a u, _ du
a de » a die, a der, a des

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: "apologien der variation _ our business convention ((a du) OR (a de)) developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: apologien der variation _ our business convention ((a du) OR (a de)) developpement en afrique.*.
