• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yan wang) OR (wang yan))) OR (yang guang)) tan hua ((pei yang) OR (hui yang)) judy long du ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yan wang) or (wang yan))) or (yang guang)) tan hua ((pei yang) OR (hui yang)) judy long du ;*".
