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