• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis new index transformers em cao ) or ( luis 1 has transformed em (acao OR macao) ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis new index transformers em cao ) or ( luis 1 has transformed em (acao OR macao) ))*.
