Perhaps you should try some spelling variations:
development eco » development second, development east, development menu
typologie die » typologie des, typologie der, theologie die
die variation » de variation, does variation, der variation
eco afrique » en afrique
dem mass » term mass, dem mis
a das » 1 das, 3 das, _ das
2 das » 1 das

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 die variation _ dem mass communication ((a das) OR (2 das)) development eco afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie die variation _ dem mass communication ((a das) OR (2 das)) development eco afrique.*.
