• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong bin) OR (dong di)) ((ji yu) OR (((a su) OR (a sum)))) cheng shuang tin hong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong bin) OR (dong di)) ((ji yu) or (((a su) or (a sum)))) cheng shuang tin hong shu ;*".
