Perhaps you should try some spelling variations:
vos communications » vs communications, laos communications, do communications
technologies 4 » technologies _
development en » developpement en, development menu, development eco
4 information » 2 information, 1 information
information 1 » information 2, information 3, information 3.2
2 vos » 2 vols, 2 von, 2 vom
1 sme » _ sme, 5 sme
3 sme » 3 same, _ sme, 3 smt

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 4 information 1 2 vos communications ((1 sme) OR (3 sme)) development en afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 4 information 1 2 vos communications ((1 sme) OR (3 sme)) development en afrique.*.
