• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (thuat san)) kho ((tang xa) OR (tang ma)) hoi. lieu va cac xuc va dinh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (thuat san)) kho ((tang xa) OR (tang ma)) hoi. lieu va cac xuc va dinh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (thuat san)) kho ((tang xa) OR (tang ma)) hoi. lieu va cac xuc va dinh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (thuat san)) kho ((tang xa) OR (tang ma)) hoi. lieu va cac xuc va dinh vi cua tre*.
