• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong yang) OR (wang liang)) ya ((hua best) OR (our best)) yang yang hoang shu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong yang) or (wang liang)) ya ((hua best) OR (our best)) yang yang hoang shu ;".
