• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"khanh duc lich.\") OR (((\"thanh duc lich.\") OR (\"than duc lich.\"))))".
• Removing quotes may allow a broader search: (( khanh duc lich. ) OR ((( thanh duc lich. ) OR ( than duc lich. )))).
• Adding a wildcard symbol may retrieve word variants: (("khanh duc lich.") OR ((("thanh duc lich.") OR ("than duc lich."))))*.
