• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yuan wang) OR (yan wang))) OR (huang cheng)) gao jia zhen zhang ying chang seo ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yuan wang) OR (yan wang))) or (huang cheng)) gao jia zhen zhang ying chang seo ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yuan wang) OR (yan wang))) or (huang cheng)) gao jia zhen zhang ying chang seo ;*.
