• If you are trying to use Boolean operators, they must be ALL CAPS: yang hong wang yuhan dan yang xi ((kang hay) OR (((kang han) OR (zhang han)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang hong wang yuhan dan yang xi ((kang hay) or (((kang han) OR (zhang han)))) ;~".
• Adding a wildcard symbol may retrieve word variants: yang hong wang yuhan dan yang xi ((kang hay) or (((kang han) OR (zhang han)))) ;*.
