• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (vu sach)) ly nang ((ma hoi) OR (mai hoi)). hieu van cam xuc va manh hai cau triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ly nang ((ma hoi) OR (mai hoi)). hieu van cam xuc va manh hai cau triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (vu sach)) ly nang ((ma hoi) OR (mai hoi)). hieu van cam xuc va manh hai cau triet".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (vu sach)) ly nang ((ma hoi) OR (mai hoi)). hieu van cam xuc va manh hai cau triet*.
