Talvez deva tentar algumas variações de ortografia:
purchase programme » purchase program (Expandir a busca), purchase programs (Expandir a busca)
decrease purchase » lease purchase (Expandir a busca), declared purchase (Expandir a busca), decrease sucrose (Expandir a busca)
decrease to » decreased to (Expandir a busca), decrease toc (Expandir a busca), decrease the (Expandir a busca)
python code » python coding (Expandir a busca), python redes (Expandir a busca)
pitons » citons (Expandir a busca), pitoni (Expandir a busca), pitoes (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease to decrease purchase programme ) OR ( python code pitons python programming ))~.
