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