• If you are trying to use Boolean operators, they must be ALL CAPS: zhang ((zhang han) OR (zhang yan)) hua gain ((((yang li) OR (yang jin))) OR (yang jie)) dang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang ((zhang han) OR (zhang yan)) hua gain ((((yang li) or (yang jin))) or (yang jie)) dang hai ;*".
