• Performing a fuzzy search may retrieve terms with similar spellings: thu ((((sach ky) OR (sach ty))) or (sach y)) lang xa hoi. hieu va dao duc va thanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((((sach ky) OR (sach ty))) OR (sach y)) lang xa hoi. hieu va dao duc va thanh vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((((sach ky) OR (sach ty))) or (sach y)) lang xa hoi. hieu va dao duc va thanh vi cua tre*".
