• Performing a fuzzy search may retrieve terms with similar spellings: te sac ((ky dang) OR (ky nang)) ((xay hoi) or (cay phoi)). thien van am thuc va hanh cac cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ((ky dang) OR (ky nang)) ((xay hoi) OR (cay phoi)). thien van am thuc va hanh cac cua triet.
