• Remover as aspas pode possibilitar buscas mais amplas: (( code resolution methods coding program ) OR ( an introduction earthen python programming ))~.
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: (("code resolution methods coding program") OR ("an introduction earthen python programming"))*.
