Perhaps you should try some spelling variations:
de developpement » sme development
developpement de » developpement des, developpement durable
apologien does » apologie des, apologien der
does variation » de variation, der variation, die variation
a do » a dot, _ do, a co
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 does variation ((a do) OR (a d)) _ communication a de developpement de l'afrique.~".
• Adding a wildcard symbol may retrieve word variants: apologien does variation ((a do) OR (a d)) _ communication a de developpement de l'afrique.*.
