• Performing a fuzzy search may retrieve terms with similar spellings: hoc thieu xanh - ((((hanh trang) OR (canh tranh))) or (thanh trung)) va nhung duong manh toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - ((((hanh trang) OR (canh tranh))) OR (thanh trung)) va nhung duong manh toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((((hanh trang) OR (canh tranh))) or (thanh trung)) va nhung duong manh toan cao".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((((hanh trang) OR (canh tranh))) or (thanh trung)) va nhung duong manh toan cao*.
