• Performing a fuzzy search may retrieve terms with similar spellings: theo ((chieu tinh) OR (chau tinh)) - ((hanh trang) or (canh tranh)) cua khong cong san than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu tinh) OR (chau tinh)) - ((hanh trang) OR (canh tranh)) cua khong cong san than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu tinh) OR (chau tinh)) - ((hanh trang) or (canh tranh)) cua khong cong san than cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu tinh) OR (chau tinh)) - ((hanh trang) or (canh tranh)) cua khong cong san than cau*.
