Perhaps you should try some spelling variations:
information series » information services, informatics series, information service
sme development » trade development
technologies a » technologies _, technologies 4, technologies 2
a information » 2 information, 1 information
development l » development li, development 1, development law
l afrique » en afrique
de et » de e, de st, dr et

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 a information series ((de et) OR (ne et)) communication _ sme development l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies a information series ((de et) OR (ne et)) communication _ sme development l afrique.*.
