• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) ((yan han) OR (huang chang)) run wage yan gang ((sung bing) OR (song bing)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) ((yan han) or (huang chang)) run wage yan gang ((sung bing) OR (song bing)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) ((yan han) or (huang chang)) run wage yan gang ((sung bing) OR (song bing)) ;*.
