• If you are trying to use Boolean operators, they must be ALL CAPS: wang yong ben ((ya gain) OR (via gain)) ying jin ((kang han) OR (kang chen)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ben ((ya gain) or (via gain)) ying jin ((kang han) OR (kang chen)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong ben ((ya gain) or (via gain)) ying jin ((kang han) OR (kang chen)) ;*.
