• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sach lo) OR (sach doi)) hang mai hoi. hieu ve cac vuc van thanh ky ((le triet) OR (ve triet))~".
• Adding a wildcard symbol may retrieve word variants: so ((sach lo) OR (sach doi)) hang mai hoi. hieu ve cac vuc van thanh ky ((le triet) OR (ve triet))*.
