• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (te sach)) lo hang ((va hoi) or (va hoa)). hieu qua nay duc va hanh vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) lo hang ((va hoi) OR (va hoa)). hieu qua nay duc va hanh vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) lo hang ((va hoi) or (va hoa)). hieu qua nay duc va hanh vai cua triet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) lo hang ((va hoi) or (va hoa)). hieu qua nay duc va hanh vai cua triet*.
