• The words AND, OR and NOT may confuse the search; try adding quotes: "%22ireland %((2 economics) or (((((2.4 economic) OR (1714 economic))) or (4 economics)))) conditions%22".
• Adding a wildcard symbol may retrieve word variants: %22ireland %((2 economics) or (((((2.4 economic) OR (1714 economic))) or (4 economics)))) conditions%22*.
