• Performing a fuzzy search may retrieve terms with similar spellings: theo chu xanh - ((((hanh tang) OR (hanh mang))) or (thanh trung)) hua khong cang tac toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - ((((hanh tang) OR (hanh mang))) OR (thanh trung)) hua khong cang tac toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - ((((hanh tang) OR (hanh mang))) or (thanh trung)) hua khong cang tac toan ban".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((((hanh tang) OR (hanh mang))) or (thanh trung)) hua khong cang tac toan ban*.
