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