Perhaps you should try some spelling variations:
time communication » de communication, mobile communication, online communication
integrating data » integration data, integrated data, integrating a
developpement l » developpement il, developpement la, developpement de
l afrique » en afrique
data 10 » data 1, data 12, data 10.4
10 time » 1 time, 13 time, 15 time
3 auf » i auf, a auf, 2 auf
b auf » i auf, a auf

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 _ integrating data 10 time communication ((3 auf) OR (b auf)) developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technology _ integrating data 10 time communication ((3 auf) OR (b auf)) developpement l afrique.*.
