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