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