Talvez deva tentar algumas variações de ortografia:
increases activity » increased activity (Expandir a busca), increases infectivity (Expandir a busca), increased activities (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
on increases » on increased (Expandir a busca), on increase (Expandir a busca), men increases (Expandir a busca)
decrease on » decrease in (Expandir a busca), decrease of (Expandir a busca), decrease and (Expandir a busca)
python api » python and (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease on increases activity program ) OR ( python api python python programming ))~.
