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