• Performing a fuzzy search may retrieve terms with similar spellings: ((wang wang) OR (wang yang)) yan lin i sang minh ((long du) or (long d)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang wang) OR (wang yang)) yan lin i sang minh ((long du) OR (long d)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) OR (wang yang)) yan lin i sang minh ((long du) or (long d)) ;*".
