• If you are trying to use Boolean operators, they must be ALL CAPS: lang ((((yan tan) OR (das clan))) OR (((yang guang) OR (yan guan)))) hsu chin hong tan yong yue ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((((yan tan) or (das clan))) or (((yang guang) OR (yan guan)))) hsu chin hong tan yong yue ;*".
