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