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
development eco » development second, development east, development menu
applications a » applications _, applications 3, applications 1
eco afrique » en afrique
a mine » _ mine, a mini, a mile
law 3 » law _, law 1
law a » law _, law 1

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