• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((ty hang) OR (ty xang)) xa hoi. hieu cao ((chat luc) or (nhan luc)) van anh lam hanh triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ty hang) OR (ty xang)) xa hoi. hieu cao ((chat luc) OR (nhan luc)) van anh lam hanh triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ty hang) OR (ty xang)) xa hoi. hieu cao ((chat luc) or (nhan luc)) van anh lam hanh triet".
• Adding a wildcard symbol may retrieve word variants: su sach ((ty hang) OR (ty xang)) xa hoi. hieu cao ((chat luc) or (nhan luc)) van anh lam hanh triet*.
