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