Talvez deva tentar algumas variações de ortografia:
defense processes » defense process (Expandir a busca), decrease processes (Expandir a busca), disease processes (Expandir a busca)
decrease defense » defense defense (Expandir a busca), decrease release (Expandir a busca), decreases disease (Expandir a busca)
ratio decrease » to decrease (Expandir a busca), rats decreases (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
action films » action fields (Expandir a busca), fiction films (Expandir a busca), active films (Expandir a busca)
films python » lines python (Expandir a busca)
node » nove (Expandir a busca), nome (Expandir a busca), none (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( node ratio decrease defense processes ) OR ( action films python python programming ))~.
