• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y sang tao khoi. lieu ha nam ((thuoc xa) OR (thuoc la)) ((van tai) or (toan tai)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y sang tao khoi. lieu ha nam ((thuoc xa) OR (thuoc la)) ((van tai) OR (toan tai)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y sang tao khoi. lieu ha nam ((thuoc xa) OR (thuoc la)) ((van tai) or (toan tai)) cua triet".
