• If you are trying to use Boolean operators, they must be ALL CAPS: wang wang ((yan li) OR (((yuan li) OR (guan li)))) le sang min ((wong shiu) OR (cong shu)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang ((yan li) or (((yuan li) OR (guan li)))) le sang min ((wong shiu) or (cong shu)) ;".
