Perhaps you should try some spelling variations:
1.1 communication » 4.1 communication, 1.3 communication, 1.4 communication
innovation space » innovation impact, innovation science, innovation sources
developpement a » developpement la, developpement de, developpement et
space spaces » spaces spaces, space space, safe spaces
spaces 1.1 » spaces 2.1
a face » a fact

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 space spaces 1.1 communication ((1 les) OR (2 les)) developpement a face.~".
• Adding a wildcard symbol may retrieve word variants: technology _ innovation space spaces 1.1 communication ((1 les) OR (2 les)) developpement a face.*.
