• The words AND, OR and NOT may confuse the search; try adding quotes: "%22ireland %((((2f economic) or (20 economic))) or (((((off economic) OR (pdf economic))) or (imf economic)))) conditions%22".
• Adding a wildcard symbol may retrieve word variants: %22ireland %((((2f economic) or (20 economic))) or (((((off economic) OR (pdf economic))) or (imf economic)))) conditions%22*.
