• Performing a fuzzy search may retrieve terms with similar spellings: hoc chieu xanh - thanh ((((trung vap) OR (trung cap))) or (trung van)) dung cong ban than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu xanh - thanh ((((trung vap) OR (trung cap))) OR (trung van)) dung cong ban than cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - thanh ((((trung vap) OR (trung cap))) or (trung van)) dung cong ban than cau*".
