• If you are trying to use Boolean operators, they must be ALL CAPS: (("basic business costs") OR ((("mail business costs") OR ("mail business case"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"basic business costs\") or (((\"mail business costs\") OR (\"mail business case\"))))*".
• Removing quotes may allow a broader search: (( basic business costs ) or ((( mail business costs ) OR ( mail business case ))))*.
