• Performing a fuzzy search may retrieve terms with similar spellings: theo chieu sach - ((hanh truong) or (manh truong)) ((cua nhung) OR (va nhung)) cong dan chan tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - ((hanh truong) OR (manh truong)) ((cua nhung) OR (va nhung)) cong dan chan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - ((hanh truong) or (manh truong)) ((cua nhung) OR (va nhung)) cong dan chan tap".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - ((hanh truong) or (manh truong)) ((cua nhung) OR (va nhung)) cong dan chan tap*.
