• Performing a fuzzy search may retrieve terms with similar spellings: ((doi chieu) OR (doc hieu)) sach - ((trinh truong) or (manh tuong)) luan nhung tuong van tuan cu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (doc hieu)) sach - ((trinh truong) OR (manh tuong)) luan nhung tuong van tuan cu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) OR (doc hieu)) sach - ((trinh truong) or (manh tuong)) luan nhung tuong van tuan cu*".
