• The words AND, OR and NOT may confuse the search; try adding quotes: "wang jane chen yulu ((tan ying) or (((tan yang) OR (dan yang)))) ((jin kang) or (john song)) yam ;~".
• Adding a wildcard symbol may retrieve word variants: wang jane chen yulu ((tan ying) or (((tan yang) OR (dan yang)))) ((jin kang) or (john song)) yam ;*.
