• If you are trying to use Boolean operators, they must be ALL CAPS: wang liang tan zhuo lee ((sang min) OR (sang minh)) ((hong ghi) OR (zhong zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang tan zhuo lee ((sang min) or (sang minh)) ((hong ghi) OR (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang tan zhuo lee ((sang min) or (sang minh)) ((hong ghi) OR (zhong zhi)) ;*.
