• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach nganh ((suc phoi) OR (luc khoi)) đong luc ) OR ( tu ban hang hoa phi đong luc ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach nganh ((suc phoi) OR (luc khoi)) đong luc ) or ( tu ban hang hoa phi đong luc ))*".
