• If you are trying to use Boolean operators, they must be ALL CAPS: ((yan liang) OR (yang yang)) tuan china ((((yi yang) OR (yin yang))) OR (du yang)) 2 long du ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan liang) or (yang yang)) tuan china ((((yi yang) OR (yin yang))) or (du yang)) 2 long du ;*".
