• Performing a fuzzy search may retrieve terms with similar spellings: tu ((((sach ty) OR (xach tay))) or (sach thu)) nang xa hoi. hieu v pham duc tan thanh dao va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((((sach ty) OR (xach tay))) OR (sach thu)) nang xa hoi. hieu v pham duc tan thanh dao va triet.
