Perhaps you should try some spelling variations:
irsn communication » iran communications, ironic communication, open communication
developpement en » developpement et, developpement des, developpement de
technologies a » technologies _, technologies 4, technologies 2
a innovation » 2 innovation, 3 innovation, 4 innovation
das irsn » das ist, did irsn
a das » 1 das, 2 das, 3 das
a aus » _ aus, i aus, 8 aus
a auf » i auf, b auf

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 a innovation a das irsn communication ((a aus) OR (a auf)) developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies a innovation a das irsn communication ((a aus) OR (a auf)) developpement en afrique.*.
