Perhaps you should try some spelling variations:
developpement use » developpement une, developpement de, development use
technologies case » technologies based, technologies can, technologies create
case information » care information, based information, phase information
gap a » gap _, gas a, gap 4
pt de » et de, pt e, pa de
pt d » pt 2, pt 1, pt 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: "technologies case information gap a _ communication ((pt de) OR (pt d)) developpement use africa.~".
• Adding a wildcard symbol may retrieve word variants: technologies case information gap a _ communication ((pt de) OR (pt d)) developpement use africa.*.
