• The words AND, OR and NOT may confuse the search; try adding quotes: "technologies 2 information content ((a et) OR (a set)) communicatione costs 2 developing a africa.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 information content ((a et) OR (a set)) communicatione costs 2 developing a africa.*.
