• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan dan dai yi ((rong minh) OR (jong min)) ((congo shu) OR (song skin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan dan dai yi ((rong minh) OR (jong min)) ((congo shu) or (song skin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan dan dai yi ((rong minh) OR (jong min)) ((congo shu) or (song skin)) ;*.
