Talvez deva tentar algumas variações de ortografia:
functioning system » sanctioning system (Expandir a busca), functioning ecosystem (Expandir a busca), sanctioning systems (Expandir a busca)
code functioning » role functioning (Expandir a busca), body functioning (Expandir a busca), couple functioning (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)
in python » _ python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

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