• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang tan huan ((jie kang) OR (jie zhang)) kim ((dong von) OR (doing von)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang tan huan ((jie kang) OR (jie zhang)) kim ((dong von) or (doing von)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang tan huan ((jie kang) OR (jie zhang)) kim ((dong von) or (doing von)) ;*.
