Perhaps you should try some spelling variations:
de communication » mobile communication, online communication
de developpement » sme development
developpement de » developpement des, developpement durable
de fabrique » la fabrique, de l'afrique
war da » war das, war data
war d » war _, war i, war a
a de » a die, a der, a des

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 _ information ((war d) OR (war da)) de communication a de developpement de fabrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies _ information ((war d) OR (war da)) de communication a de developpement de fabrique.*.
