• If you are trying to use Boolean operators, they must be ALL CAPS: jin chang chen dung ((((((un yang) OR (hui yang))) OR (du yang))) OR (tan yong)) jae song a ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "jin chang chen dung ((((((un yang) OR (hui yang))) or (du yang))) or (tan yong)) jae song a ;*".
