• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (te sach)) tu nang ma hoi. lieu ((va cam) or (va cac)) cuu ban hang di cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) tu nang ma hoi. lieu ((va cam) OR (va cac)) cuu ban hang di cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) tu nang ma hoi. lieu ((va cam) or (va cac)) cuu ban hang di cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) tu nang ma hoi. lieu ((va cam) or (va cac)) cuu ban hang di cuu tre*.
