Perhaps you should try some spelling variations:
22structural adjustment » structural adjustments, structural adjustmenton, intercultural adjustment
structure adjustment » structural adjustments, structured investment, structure alignment
2f developing » f developing, 72 developing, self developing
70 developing » 10 developing, 20 developing, 30 developing

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %((((22structural adjustment) OR (structure adjustment))) OR (structural adjustment)) %((economics public) OR (economic policy))%29 %((2f developing) OR (70 developing)) countries%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((22structural adjustment) 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 (structure adjustment))) or (structural adjustment)) %((economics public) or (economic policy))%29 %((2f developing) or (70 developing)) countries%22*.
