• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (((((dong bin) OR (dong di))) OR (dong skin)))) ya hua test strip thi hong ghi ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (((((dong bin) OR (dong di))) or (dong skin)))) ya hua test strip thi hong ghi ;".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (((((dong bin) OR (dong di))) or (dong skin)))) ya hua test strip thi hong ghi ;*.
