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