manh toan » thanh toan, anh tuan, tinh toan
ho chieu » hoc thieu, doi chieu, mot chieu

• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) xanh - hanh hang cua nhung cong ((manh toan) OR (dan toan)) cau~.
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo chieu)) xanh - hanh hang cua nhung cong ((manh toan) or (dan toan)) cau*.
