• If you are trying to use Boolean operators, they must be ALL CAPS: ((yuan kang) OR (yan wang)) tan hua ren ((yan min) OR (((yang cindy) OR (yang mind)))) hong ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan kang) or (yan wang)) tan hua ren ((yan min) or (((yang cindy) OR (yang mind)))) hong ghi ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan kang) or (yan wang)) tan hua ren ((yan min) or (((yang cindy) OR (yang mind)))) hong ghi ;*.
