• If you are trying to use Boolean operators, they must be ALL CAPS: %22ireland %((((12 economics) OR (12 economic))) OR (((14 economic) OR (((((4 economics) OR (5 economics))) OR (3 economics)))))) conditions%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22ireland %((((12 economics) OR (12 economic))) or (((14 economic) or (((((4 economics) or (5 economics))) or (3 economics)))))) conditions%22".
• Adding a wildcard symbol may retrieve word variants: %22ireland %((((12 economics) OR (12 economic))) or (((14 economic) or (((((4 economics) or (5 economics))) or (3 economics)))))) conditions%22*.
