• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu tinh) OR (cua sinh)) - hanh truong chon nhung huong ((van toan) OR (thanh toan)) cau~.
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu tinh) or (cua sinh)) - hanh truong chon nhung huong ((van toan) or (thanh toan)) cau*.
