• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yang) OR (wang yanling))) OR (((dong sign) OR (dong sin)))) a a best han minh cong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang yang) or (wang yanling))) or (((dong sign) OR (dong sin)))) a a best han minh cong hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wang yang) or (wang yanling))) or (((dong sign) OR (dong sin)))) a a best han minh cong hai ;*.
