• If you are trying to use Boolean operators, they must be ALL CAPS: wing tan tan ((b gene) OR (a gene)) ((ying jin) OR (((huang jing) OR (yang lin)))) hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing tan tan ((b gene) OR (a gene)) ((ying jin) or (((huang jing) or (yang lin)))) hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: wing tan tan ((b gene) OR (a gene)) ((ying jin) or (((huang jing) or (yang lin)))) hong hai ;*.
