• Performing a fuzzy search may retrieve terms with similar spellings: ((wang yong) or (wang yang)) ya hua gene ((yang jin) OR (yang jun)) ((jeong seo) or (jeong yeon)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yong) OR (wang yang)) ya hua gene ((yang jin) OR (yang jun)) ((jeong seo) OR (jeong yeon)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yong) or (wang yang)) ya hua gene ((yang jin) OR (yang jun)) ((jeong seo) or (jeong yeon)) ;".
• Adding a wildcard symbol may retrieve word variants: ((wang yong) or (wang yang)) ya hua gene ((yang jin) OR (yang jun)) ((jeong seo) or (jeong yeon)) ;*.
