• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dan yang) OR (wang yang))) OR (dong di)) ya ((hua rein) OR (a rein)) yang jie song shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dan yang) or (wang yang))) or (dong di)) ya ((hua rein) OR (a rein)) yang jie song shu ;*".
