• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (hoc anh)) ((ty nang) OR (ky nang)) x ho. hieu va nham thuc van anh di cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (hoc anh)) ((ty nang) OR (ky nang)) x ho. hieu va nham thuc van anh di cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (hoc anh)) ((ty nang) OR (ky nang)) x ho. hieu va nham thuc van anh di cua tre*.
