• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((lang van) OR (dang van)) hoi. hieu ve cham soc van thanh va ((cu tren) OR (la tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((lang van) OR (dang van)) hoi. hieu ve cham soc van thanh va ((cu tren) or (la tren))*".
