• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong bin) OR (((tan yong) OR (wang yang)))) yu cheng chen ((japan ii) OR (japan im)) chang hsun ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong bin) or (((tan yong) or (wang yang)))) yu cheng chen ((japan ii) OR (japan im)) chang hsun ;".
• Adding a wildcard symbol may retrieve word variants: ((dong bin) or (((tan yong) or (wang yang)))) yu cheng chen ((japan ii) OR (japan im)) chang hsun ;*.
