Perhaps you should try some spelling variations:
case information » care information, based information, phase information
technology case » technology based, technology can, technology change
communication 1 » communication _, communication a, communication 3
development en » developpement en, development menu, development eco
1 new » _ new, a new, 5 new
3 new » _ new, a new

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 case information ((1 new) OR (3 new)) _ communication 1 a development en afrique.~".
• Adding a wildcard symbol may retrieve word variants: technology case information ((1 new) OR (3 new)) _ communication 1 a development en afrique.*.
