• If you are trying to use Boolean operators, they must be ALL CAPS: ran ying ((yang liang) OR (yang li)) yi gang qiang ((hong hai) OR (zhong tai)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ran ying ((yang liang) or (yang li)) yi gang qiang ((hong hai) OR (zhong tai)) ;*".
