• If you are trying to use Boolean operators, they must be ALL CAPS: (((("world bank chief economists") OR ((("world bank how economists") OR ("world bank _ economists"))))) OR ("world beck women economic")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"world bank chief economists\") or (((\"world bank how economists\") OR (\"world bank _ economists\"))))) or (\"world beck women economic\"))".
• Removing quotes may allow a broader search: (((( world bank chief economists ) or ((( world bank how economists ) OR ( world bank _ economists ))))) or ( world beck women economic )).
