• "As palabras AND, OR e NOT podem gerar pesquisas incorrectas; tente utilizar aspas": "(((( _ natl compared case near ) OR ( 1 dna clamp _ newts ))) OR ( d daily computer cause non ))~".
• Se adicionar um carácter universal pode recuperar variações da palavra pesquisada: (((( _ natl compared case near ) OR ( 1 dna clamp _ newts ))) OR ( d daily computer cause non ))*.
