• If you are trying to use Boolean operators, they must be ALL CAPS: dong ((hoang ya) OR (hoang sy)) hua west chang min ((((hong ghi) OR (hong hai))) OR (zhong zhi)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((hoang ya) or (hoang sy)) hua west chang min ((((hong ghi) OR (hong hai))) or (zhong zhi)) ;*".
