• Performing a fuzzy search may retrieve terms with similar spellings: (("khanh du lich.") OR ((((("khanh duc lich.") OR ("khach duc lich."))) OR ("thanh duc lich."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"khanh du lich.\") OR (((((\"khanh duc lich.\") OR (\"khach duc lich.\"))) OR (\"thanh duc lich.\"))))*".
• Removing quotes may allow a broader search: (( khanh du lich. ) OR ((((( khanh duc lich. ) OR ( khach duc lich. ))) OR ( thanh duc lich. ))))*.
