Perhaps you should try some spelling variations:
kommunikation von » kommunikation und, kommunikation _, kommunikation im
developpement la » developpement de, developpement et, developpement du
e developpement » de developpement, le developpement, et developpement
technologie 1 » technologies 1, technologien 1, technologie c
la afrique » l afrique, la fabrique, en afrique
act 10 » act 16, act 10.4, act 1890
von e » von h, von i, von f

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: "technologie 1 information ((act 10) OR (act 11)) der kommunikation von e developpement la afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologie 1 information ((act 10) OR (act 11)) der kommunikation von e developpement la afrique.*.
