Perhaps you should try some spelling variations:
communication code » communications code, communication cote, communication mode
technologies can » technologies a, technologies co, technologies _
can information » von information, von informationen
d development » ed development, 1 development, led development
1 afrique » l afrique, en afrique, 1 enrique
code d » code de, code _, code 2
der 4 » der e, der a, des 4

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 can information 3.2 ((der 4) OR (der _)) communication code d development 1 afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies can information 3.2 ((der 4) OR (der _)) communication code d development 1 afrique.*.
