• If you are trying to use Boolean operators, they must be ALL CAPS: (("thu hoach doanh tri") OR ((("tu sach doanh tri") OR ("tu cac doanh tri"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"thu hoach doanh tri\") or (((\"tu sach doanh tri\") OR (\"tu cac doanh tri\"))))*".
• Removing quotes may allow a broader search: (( thu hoach doanh tri ) or ((( tu sach doanh tri ) OR ( tu cac doanh tri ))))*.
