• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ly ((hang xa) OR (hang ca)) hoi. lieu va than luc va danh lai cau triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thu sach)) ly ((hang xa) OR (hang ca)) hoi. lieu va than luc va danh lai cau triet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thu sach)) ly ((hang xa) OR (hang ca)) hoi. lieu va than luc va danh lai cau triet*.
