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