• If you are trying to use Boolean operators, they must be ALL CAPS: wang yao yang hua gene yang ((jin kong) OR (((jing fang) OR (weng fang)))) (sar OR star) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yao yang hua gene yang ((jin kong) or (((jing fang) OR (weng fang)))) (sar or star) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yao yang hua gene yang ((jin kong) or (((jing fang) OR (weng fang)))) (sar or star) ;*.
