• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong cao) OR (dann bin)) ya yuan ((wang liang) OR (wang yang)) yi hong seo ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong cao) or (dann bin)) ya yuan ((wang liang) OR (wang yang)) yi hong seo ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong cao) or (dann bin)) ya yuan ((wang liang) OR (wang yang)) yi hong seo ;*.
