• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan y juan rene ((((yan minh) OR (yuan ming))) OR (sang minh)) cong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan y juan rene ((((yan minh) OR (yuan ming))) or (sang minh)) cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan y juan rene ((((yan minh) OR (yuan ming))) or (sang minh)) cong shu ;*.
