• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang ka ((huan tao) OR (huang tao)) yang jing ((hong hai) OR (zhong tai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ka ((huan tao) OR (huang tao)) yang jing ((hong hai) or (zhong tai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ka ((huan tao) OR (huang tao)) yang jing ((hong hai) or (zhong tai)) ;*.
