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