Perhaps you should try some spelling variations:
technologies ist » technologien ist, technologies ict, technologies iot
mine development » sme development, trade development, business development
ist information » iot information, first information, cost information
applications 3 » applications _
development en » developpement en, development menu, development eco
3 mine » _ mine, a mine, 3 mise
law 3 » law _, law a
law 1 » law _, law a

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 ist information _ ((law 3) OR (law 1)) applications 3 mine development en afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies ist information _ ((law 3) OR (law 1)) applications 3 mine development en afrique.*.
