• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((((thien anh) OR (thien danh))) OR (chieu xanh)) - thanh trung va nhung cong ngan hang ca*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((thien anh) OR (thien danh))) or (chieu xanh)) - thanh trung va nhung cong ngan hang ca*".
