• If you are trying to use Boolean operators, they must be ALL CAPS: (((wang OR wan) yan) OR (yang guang)) tan china tao yang i ((long do) OR (long d)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((wang or wan) yan) or (yang guang)) tan china tao yang i ((long do) OR (long d)) ;~".
• Adding a wildcard symbol may retrieve word variants: (((wang or wan) yan) or (yang guang)) tan china tao yang i ((long do) OR (long d)) ;*.
