Perhaps you should try some spelling variations:
developpement en » developpement et, developpement des, developpement de
information act » information age, information a, information about
technologie 1 » technologies 1, technologien 1, technologie c
act 10 » act 11, act 16, act 10.4
von e » von h, von f, von r
von i » von h

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