• If you are trying to use Boolean operators, they must be ALL CAPS: (((wang OR lang) yan) OR (yang july))ng ((ya a) OR (a a)) chin chang hong ng g ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((wang OR lang) yan) or (yang july))ng ((ya a) or (a a)) chin chang hong ng g ;~".
• Adding a wildcard symbol may retrieve word variants: (((wang OR lang) yan) or (yang july))ng ((ya a) or (a a)) chin chang hong ng g ;*.
