• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (so sach)) ky lang xa hoi. hieu ((qua cam) OR (qua cham)) xuc va hanh vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ky lang xa hoi. hieu ((qua cam) OR (qua cham)) xuc va hanh vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sach)) ky lang xa hoi. hieu ((qua cam) OR (qua cham)) xuc va hanh vai cua triet".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (so sach)) ky lang xa hoi. hieu ((qua cam) OR (qua cham)) xuc va hanh vai cua triet*.
