• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong yang) OR (((yang yang) OR (wang yang)))) yao hua rene ((ten minh) OR (thi minh)) cong yu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong yang) or (((yang yang) or (wang yang)))) yao hua rene ((ten minh) OR (thi minh)) cong yu ;".
• Adding a wildcard symbol may retrieve word variants: ((dong yang) or (((yang yang) or (wang yang)))) yao hua rene ((ten minh) OR (thi minh)) cong yu ;*.
