• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) or (so sach)) ky lang ha hoi. lieu va chat xuc ((va hanh) OR (van hanh)) de va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (so sach)) ky lang ha hoi. lieu va chat xuc ((va hanh) OR (van hanh)) de va triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) or (so sach)) ky lang ha hoi. lieu va chat xuc ((va hanh) OR (van hanh)) de va triet*".
