Perhaps you should try some spelling variations:
technologies ids » technologies icts, technologies iv, technologies 3d
ids information » aids information, dis information, mis information
development eco » development second, development east, development menu
information a » information age, information about
eco afrique » en afrique
law 2.1 » law 3.1, law 2.2
law 4.1 » law 3.1

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 ids information a cge _ competition ((law 2.1) OR (law 4.1)) development eco afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies ids information a cge _ competition ((law 2.1) OR (law 4.1)) development eco afrique.*.
