• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) OR (so sach)) ky danh ma hoi. hieu va cac ((xuc va) or (luc va)) hang tai cuc tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ky danh ma hoi. hieu va cac ((xuc va) OR (luc va)) hang tai cuc tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (so sach)) ky danh ma hoi. hieu va cac ((xuc va) or (luc va)) hang tai cuc tre".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (so sach)) ky danh ma hoi. hieu va cac ((xuc va) or (luc va)) hang tai cuc tre*.
