• Performing a fuzzy search may retrieve terms with similar spellings: (("van hoi lang man.") OR ((("van hoi lang hanh.") OR ("van o lang hanh."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"van hoi lang man.\") OR (((\"van hoi lang hanh.\") OR (\"van o lang hanh.\"))))".
• Removing quotes may allow a broader search: (( van hoi lang man. ) OR ((( van hoi lang hanh. ) OR ( van o lang hanh. )))).
• Adding a wildcard symbol may retrieve word variants: (("van hoi lang man.") OR ((("van hoi lang hanh.") OR ("van o lang hanh."))))*.
