• If you are trying to use Boolean operators, they must be ALL CAPS: zhang zhang ((((yan hua) OR (tuan hua))) OR (wang hua)) rene yan ji wong sau ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang zhang ((((yan hua) OR (tuan hua))) or (wang hua)) rene yan ji wong sau ;".
