• If you are trying to use Boolean operators, they must be ALL CAPS: ((yuan kang) OR (chan kang)) qiao hua rene ((tang minh) OR (song min)) long shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan kang) OR (chan kang)) qiao hua rene ((tang minh) or (song min)) long shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan kang) OR (chan kang)) qiao hua rene ((tang minh) or (song min)) long shu ;*.
