trinh toan » tinh toan, trinh han, trinh quan
thanh toan » thanh hoa, thanh san, tinh toan
chau tinh » cuu tinh, ha tinh, cua tinh

• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu tinh) OR (chau tinh)) - canh tranh chap dang cong ((trinh toan) OR (thanh toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu tinh) OR (chau tinh)) - canh tranh chap dang cong ((trinh toan) or (thanh toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu tinh) OR (chau tinh)) - canh tranh chap dang cong ((trinh toan) or (thanh toan)) cau*.
