2f developing » f developing, 2.1 developing, self developing

• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((((22structural adjustment) OR (structural adjustmenton))) or (structure adjustment))) or (structural adjustment)) %((economics public) or (economic policy))%29 %((2f developing) or (70 developing)) countries%22".
• Adding a wildcard symbol may retrieve word variants: %((((((22structural adjustment) OR (structural adjustmenton))) or (structure adjustment))) or (structural adjustment)) %((economics public) or (economic policy))%29 %((2f developing) or (70 developing)) countries%22*.
