Perhaps you should try some spelling variations:
role development » route development, rice development, code development
competition can » competition case, competition law, competition a
development min » development main, development menu, development may
a competition » 3 competition, eu competition, a competitive
min afrique » en afrique
can role » gain role, main role, can rise
3 end » _ end, 1 end, 2 end
3 en » 3 ein, 3 den, 3 men

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 _ information ((3 en) OR (3 end)) a competition can role development min afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies _ information ((3 en) OR (3 end)) a competition can role development min afrique.*.
