Perhaps you should try some spelling variations:
time communication » de communication, mobile communication, online communication
developpement et » developpement des, developpement de, development east
formulating 4 » formulating _, formulating a, formulating g
et afrique » en afrique, l afrique
like time » time time, five time, like me
4 like » 34 like, _ like, 4 life
dr a » dr h, dr 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 _ formulating 4 like time communication ((r a) OR (dr a)) developpement et afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies _ formulating 4 like time communication ((r a) OR (dr a)) developpement et afrique.*.
