• If you are trying to use Boolean operators, they must be ALL CAPS: lang wang dong hua irene ((yang jin) OR (yang jie)) ((song sau) OR (wong sau)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang wang dong hua irene ((yang jin) or (yang jie)) ((song sau) OR (wong sau)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang wang dong hua irene ((yang jin) or (yang jie)) ((song sau) OR (wong sau)) ;*.
