• If you are trying to use Boolean operators, they must be ALL CAPS: (((("oecd economic department working papers") OR ("oecd economic department working paper"))) OR ("oecd economic department providing passes")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"oecd economic department working papers\") OR (\"oecd economic department working paper\"))) or (\"oecd economic department providing passes\"))".
• Removing quotes may allow a broader search: (((( oecd economic department working papers ) OR ( oecd economic department working paper ))) or ( oecd economic department providing passes )).
• Adding a wildcard symbol may retrieve word variants: (((("oecd economic department working papers") OR ("oecd economic department working paper"))) or ("oecd economic department providing passes"))*.
