• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong sin) OR (wang yang)) ya hua main chang won ((jeong yu) OR (jeong mi)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong sin) or (wang yang)) ya hua main chang won ((jeong yu) OR (jeong mi)) ;".
• Adding a wildcard symbol may retrieve word variants: ((dong sin) or (wang yang)) ya hua main chang won ((jeong yu) OR (jeong mi)) ;*.
