• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong hoang) OR (((yang yang) OR (wang yan)))) ((ka hua) OR (ka chuan)) ren huang thi hong ghi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong hoang) or (((yang yang) OR (wang yan)))) ((ka hua) or (ka chuan)) ren huang thi hong ghi ;*".
