• Performing a fuzzy search may retrieve terms with similar spellings: tu sach 2 dang ((xay hoi) OR (xa hoi)). hieu van ((cham xuc) or (cam xuc)) va thanh hai cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach 2 dang ((xay hoi) OR (xa hoi)). hieu van ((cham xuc) OR (cam xuc)) va thanh hai cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach 2 dang ((xay hoi) OR (xa hoi)). hieu van ((cham xuc) or (cam xuc)) va thanh hai cau treo".
• Adding a wildcard symbol may retrieve word variants: tu sach 2 dang ((xay hoi) OR (xa hoi)). hieu van ((cham xuc) or (cam xuc)) va thanh hai cau treo*.
