dong cao » dong xiao, dan cao, yong cai
dong nan » dong yang, dong sin

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong cao) OR (dong nan))) OR (dong bin)) ya hua chen yulan min jeong ghi ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong cao) OR (dong nan))) or (dong bin)) ya hua chen yulan min jeong ghi ;".
• Adding a wildcard symbol may retrieve word variants: ((((dong cao) OR (dong nan))) or (dong bin)) ya hua chen yulan min jeong ghi ;*.
