• If you are trying to use Boolean operators, they must be ALL CAPS: yang ying ya ((hua gene) OR (human gene)) ((yang min) OR (((yang jie) OR (yang jin)))) hong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang ying ya ((hua gene) OR (human gene)) ((yang min) or (((yang jie) or (yang jin)))) hong shu ;*".
