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