Perhaps you should try some spelling variations:
true communication » truth communication, time communication, stroke communication
technologies la » technologies a, technologies le, technologies lead
developpement l » developpement il, developpement la, developpement de
la formulation » la formulacion, _ formulation, la formation
doses true » doses due
l afrique » en afrique
a d2 » a d, a de, a 12

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 la formulation _ doses true communication ((a d2) OR (a 2)) developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies la formulation _ doses true communication ((a d2) OR (a 2)) developpement l afrique.*.
