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