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