• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty hang co hoi. lieu ((va chao) OR (va cao)) xu ((va hanh) or (va thanh)) vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty hang co hoi. lieu ((va chao) OR (va cao)) xu ((va hanh) OR (va thanh)) vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty hang co hoi. lieu ((va chao) OR (va cao)) xu ((va hanh) or (va thanh)) vi cuu tre".
• Adding a wildcard symbol may retrieve word variants: thu sach ty hang co hoi. lieu ((va chao) OR (va cao)) xu ((va hanh) or (va thanh)) vi cuu tre*.
