• Performing a fuzzy search may retrieve terms with similar spellings: ((dong sin) or (wang yang)) ya hua ban ((((yan jiu) OR (pang jiu))) or (yang jin)) hong yu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong sin) OR (wang yang)) ya hua ban ((((yan jiu) OR (pang jiu))) OR (yang jin)) hong yu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong sin) or (wang yang)) ya hua ban ((((yan jiu) OR (pang jiu))) or (yang jin)) hong yu ;".
• Adding a wildcard symbol may retrieve word variants: ((dong sin) or (wang yang)) ya hua ban ((((yan jiu) OR (pang jiu))) or (yang jin)) hong yu ;*.
