• If you are trying to use Boolean operators, they must be ALL CAPS: wang ping wang yan fan ((yang jin) OR (ying jin)) ((eang hay) OR (kang chen)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ping wang yan fan ((yang jin) OR (ying jin)) ((eang hay) or (kang chen)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ping wang yan fan ((yang jin) OR (ying jin)) ((eang hay) or (kang chen)) ;*.
