• Performing a fuzzy search may retrieve terms with similar spellings: su sach ly lang xa hoi. ((hieu ve) OR (hieu van)) ((cao duc) or (cao suc)) ban thanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ly lang xa hoi. ((hieu ve) OR (hieu van)) ((cao duc) OR (cao suc)) ban thanh vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ly lang xa hoi. ((hieu ve) OR (hieu van)) ((cao duc) or (cao suc)) ban thanh vai cua te*".
