Talvez deva tentar algumas variações de ortografia:
risk programming » task programming (Expandir a busca), arts programming (Expandir a busca), grid programming (Expandir a busca)
decrease risk » decreased risk (Expandir a busca), increase risk (Expandir a busca), decrease in (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
decrease std » decrease sod (Expandir a busca), decrease and (Expandir a busca), decrease at (Expandir a busca)
std decrease » to decrease (Expandir a busca), and decrease (Expandir a busca), spp decrease (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 std decrease risk programming ) OR ( python api python python programming ))~.
