Talvez deva tentar algumas variações de ortografia:
decrease their » decrease the (Expandir a busca), increase their (Expandir a busca), decreases the (Expandir a busca)
their decrease » the decrease (Expandir a busca), their disease (Expandir a busca), the decreased (Expandir a busca)
r programming » _ programming (Expandir a busca), c programming (Expandir a busca), pair programming (Expandir a busca)
python usando » python and (Expandir a busca), python estudo (Expandir a busca), python django (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
decrease r » decrease or (Expandir a busca), decrease _ (Expandir a busca), decrease β (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease their decrease r programming ) OR ( python usando python python programming ))~.
