dann bin » dong bin
gain jiu » gain job, yan jiu
jiu cong » li cong
a brain » _ brain

• Performing a fuzzy search may retrieve terms with similar spellings: ((dann bin) or (((((dong sind) OR (dong ping))) or (dong sin)))) ye a brain gain jiu cong shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((dann bin) OR (((((dong sind) OR (dong ping))) OR (dong sin)))) ye a brain gain jiu cong shu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dann bin) or (((((dong sind) OR (dong ping))) or (dong sin)))) ye a brain gain jiu cong shu ;".
• Adding a wildcard symbol may retrieve word variants: ((dann bin) or (((((dong sind) OR (dong ping))) or (dong sin)))) ye a brain gain jiu cong shu ;*.
