• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong nan) OR (dong sign)) ya hua ren can men ((hong ghi) OR (zhong zhi)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong nan) or (dong sign)) ya hua ren can men ((hong ghi) OR (zhong zhi)) ;".
• Adding a wildcard symbol may retrieve word variants: ((dong nan) or (dong sign)) ya hua ren can men ((hong ghi) OR (zhong zhi)) ;*.
