Perhaps you should try some spelling variations:
au developpement » du developpement, de developpement, le developpement
developpement l » developpement il, developpement la, developpement de
technology 1 » technology _
1 inflation » 10 inflation, 12 inflation, _ inflation
l afrique » en afrique
a prices » 2 prices, gas prices, tea prices
costs au » costs a, costs amy, costs _
a price » a primer

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 1 inflation ((a prices) OR (a price)) _ communication costs au developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technology 1 inflation ((a prices) OR (a price)) _ communication costs au developpement l afrique.*.
