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