Perhaps you should try some spelling variations:
employment development » development development, environment development, component development
employee development » iphone development
regional economic » regional economics
global economic » global economy
legal economic » local economic, special economic, general economic
unemployment » deployment

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: oecd ((legal economic) OR (((global economic) OR (regional economic)))) AND ((((employment development) OR (employment unemployment))) OR (employee development)) (leed) working (paper OR papers).
• The words AND, OR and NOT may confuse the search; try adding quotes: "oecd ((legal economic) or (((global economic) OR (regional economic)))) and ((((employment development) or (employment unemployment))) or (employee development)) (leed) working (paper or papers)".
• Adding a wildcard symbol may retrieve word variants: oecd ((legal economic) or (((global economic) OR (regional economic)))) and ((((employment development) or (employment unemployment))) or (employee development)) (leed) working (paper or papers)*.
