• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - anh ((nang su) OR (nang du)) thong huong ((dan chan) OR (ban than)) cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - anh ((nang su) OR (nang du)) thong huong ((dan chan) or (ban than)) cao".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - anh ((nang su) OR (nang du)) thong huong ((dan chan) or (ban than)) cao*.
