• Remover as aspas pode possibilitar buscas mais amplas: (( coder code mining project problem ) OR ( _ python python python programming ))~.
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: (("coder code mining project problem") OR ("_ python python python programming"))*.
