• If you are trying to use Boolean operators, they must be ALL CAPS: ((thi chieu) OR (ho chieu)) xanh - hanh tang cua bang song ((tan toan) OR (tan tran)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thi chieu) or (ho chieu)) xanh - hanh tang cua bang song ((tan toan) OR (tan tran)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((thi chieu) or (ho chieu)) xanh - hanh tang cua bang song ((tan toan) OR (tan tran)) cau*.
