Perhaps you should try some spelling variations:
compensations 1 » compensations _, compensation _, compensation 4
a developpement » au developpement, de developpement, le developpement
innovation 4 » innovation _, innovation a, innovation 1
des africa » does africa, yes africa, de africa
time die » time time, time done, time d2b
time de » estime de, time done, time d2b

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: "technology _ innovation 4 ((time de) OR (time die)) compensations 1 a developpement des africa.~".
• Adding a wildcard symbol may retrieve word variants: technology _ innovation 4 ((time de) OR (time die)) compensations 1 a developpement des africa.*.
