• Performing a fuzzy search may retrieve terms with similar spellings: ((((dong yang) or (((dan yang) OR (yang yang))))) or (wang yang)) ya hua gene yang jin hong ghi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong yang) OR (((dan yang) OR (yang yang))))) OR (wang yang)) ya hua gene yang jin hong ghi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong yang) or (((dan yang) OR (yang yang))))) or (wang yang)) ya hua gene yang jin hong ghi ;*".
