• If you are trying to use Boolean operators, they must be ALL CAPS: lang ((((((yan yang) OR (yao yang))) OR (yang yang))) OR (tan yang)) li lee sing hong ng shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((((((yan yang) OR (yao yang))) or (yang yang))) or (tan yang)) li lee sing hong ng shu ;*".
