Perhaps you should try some spelling variations:
developpement en » developpement et, developpement des, developpement de
does business » des business, smes business, das business
de variation » der variation, die variation, does variation
apologia de » tipologia de, apologie des, apologia _
a set » _ set
a et » a net, a bet, a jet

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: "apologia de variation _ does business community ((a et) OR (a set)) developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: apologia de variation _ does business community ((a et) OR (a set)) developpement en afrique.*.
