Talvez deva tentar algumas variações de ortografia:
testing programs » teaching programs (Expandir a busca), feeding programs (Expandir a busca), training programs (Expandir a busca)
release testing » release using (Expandir a busca), release tests (Expandir a busca), release coating (Expandir a busca)
decrease rate » decreased rate (Expandir a busca), decreases rate (Expandir a busca), decrease at (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
rate release » water release (Expandir a busca), atp release (Expandir a busca), male release (Expandir a busca)
python code » python coding (Expandir a busca), python redes (Expandir a busca)
code python » codigo python (Expandir a busca), pacote python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease rate release testing programs ) OR ( python code python python programming ))~.
