• If you are trying to use Boolean operators, they must be ALL CAPS: oecd legal economic AND ((((((development development) OR (development developing))) OR (development environment))) OR (environment development)) (leed) working papers.
• The words AND, OR and NOT may confuse the search; try adding quotes: "oecd legal economic and ((((((development development) OR (development developing))) or (development environment))) or (environment development)) (leed) working papers".
• Adding a wildcard symbol may retrieve word variants: oecd legal economic and ((((((development development) OR (development developing))) or (development environment))) or (environment development)) (leed) working papers*.
