• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu ((sach thanh) OR (sach tranh)) hoa khi đong luc ) OR ( su danh thanh hoa phi đong luc ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu ((sach thanh) OR (sach tranh)) hoa khi đong luc ) or ( su danh thanh hoa phi đong luc ))*".
