• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang wang hui rene ((((yan minh) OR (sang minh))) OR (anh minh)) ((hong ghi) OR (hong g)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang wang hui rene ((((yan minh) OR (sang minh))) or (anh minh)) ((hong ghi) or (hong g)) ;*".
