Perhaps you should try some spelling variations:
environment development » development development
employee development » iphone development
global economic » global economy, regional economic
social economic » socio economic, social economy, social ecological
legal economic » regional economic, special economic, general economic
local economic » special economic
working papers » working paper

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