Perhaps you should try some spelling variations:
2.2 economic » 12 economic, 2 economics, 12 economics
14 economics » 1 economics, 5 economics, 3 economics
14 economic » 4 economic
4 economics » 4 economic, 1 economics, 5 economics

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: %22ireland %((2.2 economic) OR (((((14 economics) OR (14 economic))) OR (4 economics)))) conditions%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22ireland %((2.2 economic) or (((((14 economics) OR (14 economic))) or (4 economics)))) conditions%22".
• Adding a wildcard symbol may retrieve word variants: %22ireland %((2.2 economic) or (((((14 economics) OR (14 economic))) or (4 economics)))) conditions%22*.
