• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (thuat lanh)) v nang xa hoi. lieu va tham ((hoc va) OR (loc va)) hanh di cau treo.
• Adding a wildcard symbol may retrieve word variants: ((thu sach) or (thuat lanh)) v nang xa hoi. lieu va tham ((hoc va) or (loc va)) hanh di cau treo*.
