• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yang wang) OR (yan wang)) zhi west yang jui ((((won sau) OR (wong sau))) OR (non state)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang wang) OR (yan wang)) zhi west yang jui ((((won sau) or (wong sau))) or (non state)) ;".
• Adding a wildcard symbol may retrieve word variants: wang ((yang wang) OR (yan wang)) zhi west yang jui ((((won sau) or (wong sau))) or (non state)) ;*.
