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