• The words AND, OR and NOT may confuse the search; try adding quotes: "(wan OR lang) ((yan yan) OR (qian yan)) china law yong lin ((long han) OR (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wan OR lang) ((yan yan) OR (qian yan)) china law yong lin ((long han) OR (zhong zhi)) ;*.
