• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang jia ((((i gene) OR (e gene))) OR (iii gene)) song min ((jeong ghi) OR (jeong su)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yang jia ((((i gene) or (e gene))) or (iii gene)) song min ((jeong ghi) or (jeong su)) ;*.
