• If you are trying to use Boolean operators, they must be ALL CAPS: thu san ky nang ((ma hoi) OR (ma hoa)). ((hieu van) OR (thien van)) nam qua ban hang vai cac 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) OR (thien van)) nam qua ban hang vai cac treo".
• Adding a wildcard symbol may retrieve word variants: thu san ky nang ((ma hoi) or (ma hoa)). ((hieu van) OR (thien van)) nam qua ban hang vai cac treo*.
