• As palavras AND, OR e NOT pode ocasionar problemas na busca; tente utilizar as aspas: "((\"co optimizing control coding program\") OR (\"_ python python python programming\"))~".
• Remover as aspas pode possibilitar buscas mais amplas: (( co optimizing control coding program ) OR ( _ python python python programming ))~.
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: (("co optimizing control coding program") OR ("_ python python python programming"))*.
