• Remover as aspas pode possibilitar buscas mais amplas: (( teaching cooperative in loading program ) OR ( engine optimization python computer program ))~.
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: (("teaching cooperative in loading program") OR ("engine optimization python computer program"))*.
