• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty sang xa hoi. thien van ((cam duc) OR (cao duc)) ((va danh) or (va kinh)) lai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty sang xa hoi. thien van ((cam duc) OR (cao duc)) ((va danh) OR (va kinh)) lai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty sang xa hoi. thien van ((cam duc) OR (cao duc)) ((va danh) or (va kinh)) lai cuu tre*".
