• If you are trying to use Boolean operators, they must be ALL CAPS: ((((tu sach) OR (tu cach))) OR (te sach)) ky nang ma hoi. hieu van chat loc va danh di cua tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((tu sach) OR (tu cach))) or (te sach)) ky nang ma hoi. hieu van chat loc va danh di cua tu~".
• Adding a wildcard symbol may retrieve word variants: ((((tu sach) OR (tu cach))) or (te sach)) ky nang ma hoi. hieu van chat loc va danh di cua tu*.
