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