• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong yang) OR (yang yang)) yi hua ((gene bank) OR (one bank)) min hong ghi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong yang) or (yang yang)) yi hua ((gene bank) OR (one bank)) min hong ghi ;*".
