• The words AND, OR and NOT may confuse the search; try adding quotes: "technology service information d820 ((pt a) OR (pt 2)) communicative _ sme development l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technology service information d820 ((pt a) OR (pt 2)) communicative _ sme development l afrique.*.
