• Performing a fuzzy search may retrieve terms with similar spellings: vu ((sach dao) OR (lanh dao)) ((lang xa) or (nang ma)) hoi. hieu ve cam luc va danh vi va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sach dao) OR (lanh dao)) ((lang xa) OR (nang ma)) hoi. hieu ve cam luc va danh vi va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sach dao) OR (lanh dao)) ((lang xa) or (nang ma)) hoi. hieu ve cam luc va danh vi va triet".
• Adding a wildcard symbol may retrieve word variants: vu ((sach dao) OR (lanh dao)) ((lang xa) or (nang ma)) hoi. hieu ve cam luc va danh vi va triet*.
