• If you are trying to use Boolean operators, they must be ALL CAPS: ((nho chieu) OR (ho chieu)) sang - ((thanh trung) OR (thanh tung)) va dung trong thanh tran thanh.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nho chieu) OR (ho chieu)) sang - ((thanh trung) or (thanh tung)) va dung trong thanh tran thanh".
