• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky dang van hoi. hieu ((van cam) OR (van nam)) luc va ((danh dinh) OR (danh vinh)) cuu treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky dang van hoi. hieu ((van cam) or (van nam)) luc va ((danh dinh) OR (danh vinh)) cuu treo".
• Adding a wildcard symbol may retrieve word variants: tu sach ky dang van hoi. hieu ((van cam) or (van nam)) luc va ((danh dinh) OR (danh vinh)) cuu treo*.
