• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang OR wing) OR lang) ((wang chi) OR (wang chau)) yu cheng leong ji zhang zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang or wing) or lang) ((wang chi) OR (wang chau)) yu cheng leong ji zhang zhi ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang or wing) or lang) ((wang chi) OR (wang chau)) yu cheng leong ji zhang zhi ;*.
