• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky lang xa hoi. hieu ((van cac) or (((van hoc) OR (van hoa)))) trung ha danh lai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky lang xa hoi. hieu ((van cac) OR (((van hoc) OR (van hoa)))) trung ha danh lai cua te.
