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