• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (so sach)) ty ((lang xa) OR (lang ha)) hoi. lieu va dau tuc ban thanh di cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ty ((lang xa) OR (lang ha)) hoi. lieu va dau tuc ban thanh di cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sach)) ty ((lang xa) OR (lang ha)) hoi. lieu va dau tuc ban thanh di cuu tre*".
