• If you are trying to use Boolean operators, they must be ALL CAPS: wang kang tuan ((hua gain) OR (run gain)) ((yang min) OR (yang jin)) young man ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang kang tuan ((hua gain) OR (run gain)) ((yang min) or (yang jin)) young man ;~".
• Adding a wildcard symbol may retrieve word variants: wang kang tuan ((hua gain) OR (run gain)) ((yang min) or (yang jin)) young man ;*.
