• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) ((wang xuan) OR (((yan guan) OR (gan guan)))) vu irene ying john song shin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) ((wang xuan) or (((yan guan) OR (gan guan)))) vu irene ying john song shin ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) ((wang xuan) or (((yan guan) OR (gan guan)))) vu irene ying john song shin ;*.
