• Performing a fuzzy search may retrieve terms with similar spellings: cho chu xanh - ((hanh hang) OR (thanh hang)) ca khong thong ((san toan) or (dan toan)) cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: cho chu xanh - ((hanh hang) OR (thanh hang)) ca khong thong ((san toan) OR (dan toan)) cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho chu xanh - ((hanh hang) OR (thanh hang)) ca khong thong ((san toan) or (dan toan)) cao".
• Adding a wildcard symbol may retrieve word variants: cho chu xanh - ((hanh hang) OR (thanh hang)) ca khong thong ((san toan) or (dan toan)) cao*.
