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