hach toan » thanh toan, manh toan
ho chieu » theo chieu, doi chieu, mot chieu

• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) sang - ((hanh trinh) OR (canh tranh)) quan ban cong hach toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (hoc thieu)) sang - ((hanh trinh) or (canh tranh)) quan ban cong hach toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (hoc thieu)) sang - ((hanh trinh) or (canh tranh)) quan ban cong hach toan tap*.
