• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan wang) OR (wen wang)) yan a gene how ((man one) OR (many one)) (sau OR saur) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan wang) or (wen wang)) yan a gene how ((man one) OR (many one)) (sau or saur) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan wang) or (wen wang)) yan a gene how ((man one) OR (many one)) (sau or saur) ;*.
