• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong yang) OR (((among sign) OR (among syrian)))) ya ((hua chen) OR (a chen)) yan tin hong ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong yang) or (((among sign) or (among syrian)))) ya ((hua chen) OR (a chen)) yan tin hong ghi ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong yang) or (((among sign) or (among syrian)))) ya ((hua chen) OR (a chen)) yan tin hong ghi ;*.
