• If you are trying to use Boolean operators, they must be ALL CAPS: ((thuoc sach) OR (te sach)) ky nang x hoi. hieu ve cam xuc ((van hanh) OR (van anh)) vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thuoc sach) or (te sach)) ky nang x hoi. hieu ve cam xuc ((van hanh) OR (van anh)) vi cua te".
• Adding a wildcard symbol may retrieve word variants: ((thuoc sach) or (te sach)) ky nang x hoi. hieu ve cam xuc ((van hanh) OR (van anh)) vi cua te*.
