b informationen » _ informationen, av informationen, b information
informationen 2 » informationen zu, information 2, informationen und
o developpement » ou developpement, de developpement, le developpement
technologies b » technologies _, technologies 4, technologies 2
il afrique » l afrique, en afrique
do 5.4 » do 5.2, go 5.4, do 7.5.4
a o » a co

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 b informationen 2 ((do 5.4) OR (df 5.4)) communication a o developpement il afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies b informationen 2 ((do 5.4) OR (df 5.4)) communication a o developpement il afrique.*.
