• "As palabras AND, OR e NOT podem gerar pesquisas incorrectas; tente utilizar aspas": "(( j current nerve best due ) OR ( le affect neural based dti ))~".
• Se adicionar um carácter universal pode recuperar variações da palavra pesquisada: (( j current nerve best due ) OR ( le affect neural based dti ))*.
