• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu xanh - ((((canh manh) OR (van manh))) or (lanh manh)) cua dung nguon van toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((((canh manh) OR (van manh))) OR (lanh manh)) cua dung nguon van toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((((canh manh) OR (van manh))) or (lanh manh)) cua dung nguon van toan cao".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((((canh manh) OR (van manh))) or (lanh manh)) cua dung nguon van toan cao*.
