• If you are trying to use Boolean operators, they must be ALL CAPS: (("tu bach mai ban nguoi") OR ((("so sach va con nguoi") OR ("su cac bai cho nguoi"))))~.
• Removing quotes may allow a broader search: (( tu bach mai ban nguoi ) or ((( so sach va con nguoi ) or ( su cac bai cho nguoi ))))~.
• Adding a wildcard symbol may retrieve word variants: (("tu bach mai ban nguoi") or ((("so sach va con nguoi") or ("su cac bai cho nguoi"))))*.
