• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty lang ha hoi. hieu va ((((nam thuc) OR (nam thuoc))) OR (am thuc)) va danh vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty lang ha hoi. hieu va ((((nam thuc) OR (nam thuoc))) or (am thuc)) va danh vai cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ty lang ha hoi. hieu va ((((nam thuc) OR (nam thuoc))) or (am thuc)) va danh vai cua triet*.
