Perhaps you should try some spelling variations:
communication pt » communication 3, communication 1, communication 2
sme development » trade development
development did » development desd, development d, development doi
technologies 1 » technologies _, technologies 4, technologies 2
information a » information age, information about
pt sme » pt semen

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 1 information a ((des 3) OR (des _)) communication pt sme development did afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 1 information a ((des 3) OR (des _)) communication pt sme development did afrique.*.
