Perhaps you should try some spelling variations:
technologies cost » technologies co, technologies case, technologies cohort
cost information » postal information, about information, asset information
20 dervelopment » 20 development, 2 development, 10 development
dervelopment en » developpement en, development menu, development eco
applications 3 » applications _
3 das » 2 das
3 20 » _ 20, 3 2, g 20

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 cost information ((3 das) OR (1 das)) _ applications 3 20 dervelopment en afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies cost information ((3 das) OR (1 das)) _ applications 3 20 dervelopment en afrique.*.
