Perhaps you should try some spelling variations:
et developpement » de developpement, le developpement, test development
developpement l » developpement il, developpement la, developpement de
technology 3 » technology _, technology 1, technology 4
3 inflation » _ inflation, 2 inflation, 6 inflation
tax spaces » tax space, six spaces
tax sales » tax rules, gas sales, car sales
l afrique » en afrique
a et » a set, a net, a bet

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 3 inflation ((tax spaces) OR (tax sales)) _ communication a et developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technology 3 inflation ((tax spaces) OR (tax sales)) _ communication a et developpement l afrique.*.
