• If you are trying to use Boolean operators, they must be ALL CAPS: su ((((sach ty) OR (sach tu))) OR (sach y)) hang van hoi. hieu van cau tuc va nang ji su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((((sach ty) OR (sach tu))) or (sach y)) hang van hoi. hieu van cau tuc va nang ji su triet".
• Adding a wildcard symbol may retrieve word variants: su ((((sach ty) OR (sach tu))) or (sach y)) hang van hoi. hieu van cau tuc va nang ji su triet*.
