• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) xanh - hanh tinh ((cua tuong) OR (cua huong)) luong va toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chieu)) xanh - hanh tinh ((cua tuong) OR (cua huong)) luong va toan ban".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo chieu)) xanh - hanh tinh ((cua tuong) OR (cua huong)) luong va toan ban*.
