• Performing a fuzzy search may retrieve terms with similar spellings: hoc hieu manh - cang thang va dung ((cong tan) or (((song van) OR (duong van)))) thanh mau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hieu manh - cang thang va dung ((cong tan) OR (((song van) OR (duong van)))) thanh mau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hieu manh - cang thang va dung ((cong tan) or (((song van) OR (duong van)))) thanh mau*".
