• If you are trying to use Boolean operators, they must be ALL CAPS: wang yao ((yang lin) OR (wang lin)) ((kim song) OR (((jin song) OR (jie song)))) minh long shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yao ((yang lin) OR (wang lin)) ((kim song) or (((jin song) or (jie song)))) minh long shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yao ((yang lin) OR (wang lin)) ((kim song) or (((jin song) or (jie song)))) minh long shu ;*.
