• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((((sach ky) OR (sach y))) OR (sac ky)) tang xa hoi. hieu ve cac lo van anh giau cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((((sach ky) OR (sach y))) or (sac ky)) tang xa hoi. hieu ve cac lo van anh giau cua tre".
• Adding a wildcard symbol may retrieve word variants: tu ((((sach ky) OR (sach y))) or (sac ky)) tang xa hoi. hieu ve cac lo van anh giau cua tre*.
