• Performing a fuzzy search may retrieve terms with similar spellings: toc sach ((y lang) OR (o lang)) ha hoi. thien van cam luc va thanh ((trinh cua) or (trinh luat)) tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ((y lang) OR (o lang)) ha hoi. thien van cam luc va thanh ((trinh cua) OR (trinh luat)) tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ((y lang) OR (o lang)) ha hoi. thien van cam luc va thanh ((trinh cua) or (trinh luat)) tu".
• Adding a wildcard symbol may retrieve word variants: toc sach ((y lang) OR (o lang)) ha hoi. thien van cam luc va thanh ((trinh cua) or (trinh luat)) tu*.
