• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yong yang) OR (ying yang)) ii cost savings using ((congo bi) OR (congo 1)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong yang) or (ying yang)) ii cost savings using ((congo bi) OR (congo 1)) ;*".
