• If you are trying to use Boolean operators, they must be ALL CAPS: lang wang yong hua chen yan ((((jin song) OR (jie song))) OR (john wong)) sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang wang yong hua chen yan ((((jin song) OR (jie song))) or (john wong)) sau ;~".
• Adding a wildcard symbol may retrieve word variants: lang wang yong hua chen yan ((((jin song) OR (jie song))) or (john wong)) sau ;*.
