Perhaps you should try some spelling variations:
formationen als » informationen als, formationen des, informationen aus
communication 2 » communication _, communication a, communication 3
pss development » less development, gas development, its development
technologies 2 » technologies _, technologies 4
2 formationen » _ informationen, b informationen, 2 formative
1 afrique » l afrique, en afrique, 1 enrique
mdg 1 » sdg 1
2 pss » _ pss, 2 dss, 2 mss

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: "technologies 2 formationen als ((mdg 1) OR (mdg _)) communication 2 pss development 1 afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 formationen als ((mdg 1) OR (mdg _)) communication 2 pss development 1 afrique.*.
