• The words AND, OR and NOT may confuse the search; try adding quotes: "technologies 8 connecting features ((gas 4) OR (gas a)) communication 3 sme development 1 afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 8 connecting features ((gas 4) OR (gas a)) communication 3 sme development 1 afrique.*.
