• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan ((yang yi) OR (((yang yin) OR (yang jin)))) cheng ying jin wong sau ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((yang yi) or (((yang yin) OR (yang jin)))) cheng ying jin wong sau ;".
