Perhaps you should try some spelling variations:
4.2 developpement » 4.2 development, de developpement, le developpement
developpement de » developpement des, developpement durable
technology road » technology role, technology roadmap, technology robot
road inflation » read inflation, food inflation, road information
inflation 1 » inflation _, inflation a, inflation tax
de fabrice » die fabrics, avec fabrice, die fabriken
fig 4 » fig 1, big 4, fig 3
fig 2 » fig 1, fig 3

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 road inflation 1 ((fig 4) OR (fig 2)) communication costs 4.2 developpement de fabrice.~".
• Adding a wildcard symbol may retrieve word variants: technology road inflation 1 ((fig 4) OR (fig 2)) communication costs 4.2 developpement de fabrice.*.
