• If you are trying to use Boolean operators, they must be ALL CAPS: dong zhang tan yu chen yang ((((min cong) OR (min hong))) OR (((amin hong) OR (tin hong)))) shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong zhang tan yu chen yang ((((min cong) OR (min hong))) or (((amin hong) or (tin hong)))) shu ;~".
• Adding a wildcard symbol may retrieve word variants: dong zhang tan yu chen yang ((((min cong) OR (min hong))) or (((amin hong) or (tin hong)))) shu ;*.
