• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang OR wan) OR lang) ((nan yan) OR (qian yan)) yuan meng wong john wong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang or wan) or lang) ((nan yan) OR (qian yan)) yuan meng wong john wong siu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang or wan) or lang) ((nan yan) OR (qian yan)) yuan meng wong john wong siu ;*.
