• If you are trying to use Boolean operators, they must be ALL CAPS: tan yang ying hua ren ((((yan jiu) OR (yang jin))) OR (yang jun)) ((long shu) OR (long du)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tan yang ying hua ren ((((yan jiu) OR (yang jin))) or (yang jun)) ((long shu) or (long du)) ;".
