Perhaps you should try some spelling variations:
csr communication » de communication, 3 communication, 4 communication
developpement l » developpement il, developpement la, developpement de
technologies 2 » technologies _, technologies 4
information pt » information part, information 1, information 1.2
l afrique » en afrique
de csr » der csr, does csr
pt de » et de, pt d, pt e

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 2 information pt de csr communication ((a l) OR (a la)) developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 information pt de csr communication ((a l) OR (a la)) developpement l afrique.*.
