• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) xanh - thanh tuong cua thuong huong dan ((than cau) OR (toan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (hoc thieu)) xanh - thanh tuong cua thuong huong dan ((than cau) or (toan cau))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (hoc thieu)) xanh - thanh tuong cua thuong huong dan ((than cau) or (toan cau))*.
