Perhaps you should try some spelling variations:
de communication » mobile communication, online communication
de developpement » sme development
developpement en » developpement et, developpement des, developpement de
technology 2 » technology _, technology 1, technology 3
2 inflation » 12 inflation, _ inflation, 6 inflation
a de » a die, a der, a des

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 2 inflation ((a price) OR (a primer)) de communication a de developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: technology 2 inflation ((a price) OR (a primer)) de communication a de developpement en afrique.*.
