Talvez deva tentar algumas variações de ortografia:
replication system » application system (Expandir a busca), application systems (Expandir a busca), medication system (Expandir a busca)
code replication » coded replication (Expandir a busca), code application (Expandir a busca), code applications (Expandir a busca)
system decrease » system decreases (Expandir a busca), system increase (Expandir a busca), symptom decrease (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
code code » code cdc (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code code replication system decrease ) OR ( _ python python python programming ))~.
