• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yuan wang) OR (yan wang))) OR (yuan cheng)) liang xi gene hong than wong sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yuan wang) OR (yan wang))) or (yuan cheng)) liang xi gene hong than wong sau ;*".
