• Performing a fuzzy search may retrieve terms with similar spellings: theo ((cao sach) or (hoc sach)) - ((manh truong) OR (manh trung)) cua dang cong dan toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((cao sach) OR (hoc sach)) - ((manh truong) OR (manh trung)) cua dang cong dan toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((cao sach) or (hoc sach)) - ((manh truong) OR (manh trung)) cua dang cong dan toan cao*".
