technologies 2 » technologies _, technologies 4
information 3 » information 2
development l » development li, development 1, development law
l afrique » en afrique
how sme » how some, how she, how safe
der 3 » der e, des 3, der 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 2 information 3 ((der 3) OR (der _)) competition how sme development l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 information 3 ((der 3) OR (der _)) competition how sme development l afrique.*.
