Perhaps you should try some spelling variations:
communication skills » communication services, communication systems
un communication » 3 communication, 4 communication, 1 communication
developpement et » developpement des, developpement de, development east
b developpement » de developpement, le developpement, et developpement
technologies 1 » technologies _, technologies 4, technologies 2
skills b » skills _, skills a, skills 1
et fairs » et faire, art fairs, _ fairs
3 die » 2 die
_ die » 2 die

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 die) OR (_ die)) un communication skills b developpement et fairs.~".
• Adding a wildcard symbol may retrieve word variants: technologies 1 information ((3 die) OR (_ die)) un communication skills b developpement et fairs.*.
