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