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