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