• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ly ((sang ma) or (nang cao)) hoi. thien van cam tuc ((xa dang) OR (da dang)) hai cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ly ((sang ma) OR (nang cao)) hoi. thien van cam tuc ((xa dang) OR (da dang)) hai cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ly ((sang ma) or (nang cao)) hoi. thien van cam tuc ((xa dang) OR (da dang)) hai cau treo".
• Adding a wildcard symbol may retrieve word variants: vu sach ly ((sang ma) or (nang cao)) hoi. thien van cam tuc ((xa dang) OR (da dang)) hai cau treo*.
