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