• If you are trying to use Boolean operators, they must be ALL CAPS: thu san ky nang ((ma hoi) OR (ma hoa)). hieu van ((nam dua) OR (nam mua)) ban hang vai cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu san ky nang ((ma hoi) or (ma hoa)). hieu van ((nam dua) OR (nam mua)) ban hang vai cau treo".
• Adding a wildcard symbol may retrieve word variants: thu san ky nang ((ma hoi) or (ma hoa)). hieu van ((nam dua) OR (nam mua)) ban hang vai cau treo*.
