Perhaps you should try some spelling variations:
developpement de » developpement des, developpement durable
ab developpement » au developpement, de developpement, le developpement
data conclusion » data conclusions, a conclusion, media conclusion
conclusion from » conclusions from
technologies 1 » technologies _, technologies 4, technologies 2
de afrique » de l'afrique, en afrique, l afrique
from ab » from a, from ad, from abcs
3 el » y el
_ el » _ eu, _ e, _ ex

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 1 information ((3 el) OR (_ el)) data conclusion from ab developpement de afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 1 information ((3 el) OR (_ el)) data conclusion from ab developpement de afrique.*.
