Perhaps you should try some spelling variations:
developpement et » developpement des, developpement de, development east
von information » von informationen, can information
1 developpement » de developpement, le developpement, et developpement
technology von » technology vi, technology vt, technology vision
et afrique » en afrique, l afrique
works und » works under, works united
works up » workers up, works bpp, works tcp

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: "technology von information _ great ((works und) OR (works up)) schluss 1 developpement et afrique.~".
• Adding a wildcard symbol may retrieve word variants: technology von information _ great ((works und) OR (works up)) schluss 1 developpement et afrique.*.
