• If you are trying to use Boolean operators, they must be ALL CAPS: wang jing tan ((w gene) OR (e gene)) tang kin ((jeong mi) OR (jeong 情)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang jing tan ((w gene) or (e gene)) tang kin ((jeong mi) OR (jeong 情)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang jing tan ((w gene) or (e gene)) tang kin ((jeong mi) OR (jeong 情)) ;*.
