Perhaps you should try some spelling variations:
oral communication » personal communication
technologies more » technologies market, technologies co, technologies art
more information » price information, trade information
same development » sme development, game development, safe development
1 afrique » l afrique, en afrique, 1 enrique
pt 4 » 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 more information ((pt 4) OR (pt 2)) oral communication _ same development 1 afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies more information ((pt 4) OR (pt 2)) oral communication _ same development 1 afrique.*.
