• Performing a fuzzy search may retrieve terms with similar spellings: toc sach y sang ma hoi. thien van ((cam duc) OR (pham duc)) va tinh lao ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach y sang ma hoi. thien van ((cam duc) OR (pham duc)) va tinh lao ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach y sang ma hoi. thien van ((cam duc) OR (pham duc)) va tinh lao ((cua tre) or (cua triet))*".
