• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (yuan kang)) wang hui chen ((chung hsuan) OR (chang hsun)) long seo ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (yuan kang)) wang hui chen ((chung hsuan) OR (chang hsun)) long seo ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (yuan kang)) wang hui chen ((chung hsuan) OR (chang hsun)) long seo ;*.
