• If you are trying to use Boolean operators, they must be ALL CAPS: %((((22structural adjustment) OR (structural adjustments))) OR (structural adjustment)) %28economic policy%29 %2f developing countries%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((22structural adjustment) OR (structural adjustments))) or (structural adjustment)) %28economic policy%29 %2f developing countries%22*".
