• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ty) OR (sach tu)) lang ha hoi. hieu ve cham lo ((va danh) OR (va dinh)) lai chau te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ty) OR (sach tu)) lang ha hoi. hieu ve cham lo ((va danh) or (va dinh)) lai chau te".
• Adding a wildcard symbol may retrieve word variants: su ((sach ty) OR (sach tu)) lang ha hoi. hieu ve cham lo ((va danh) or (va dinh)) lai chau te*.
