Perhaps you should try some spelling variations:
"communication de l'entreprise" » "communication des l'entreprise", "communication die l'entreprise", "communication do l'entreprise", "communication dans l'entreprise"
"communication a l'entreprise" » "communication dans l'entreprise"

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: "((\"communication a l'entreprise\") OR (\"communication de l'entreprise\"))".
• Removing quotes may allow a broader search: (( communication a l'entreprise ) OR ( communication de l'entreprise )).
• Adding a wildcard symbol may retrieve word variants: (("communication a l'entreprise") OR ("communication de l'entreprise"))*.
