Perhaps you should try some spelling variations:
variation series » education series, action series, edition series
development mega » development legal, development media, development menu
typologie de » typologie des, typologie der, typologien der
de variation » der variation, die variation, does variation
mega afrique » en afrique
a based » a biased, na based, 3 based
a base » la base

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 series ((a based) OR (a base)) communication _ a development mega afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie de variation series ((a based) OR (a base)) communication _ a development mega afrique.*.
