Talvez deva tentar algumas variações de ortografia:
decrease placement » decreased platelet (Expandir a busca), desse placement (Expandir a busca)
placement program » placement problem (Expandir a busca), payment program (Expandir a busca), enhancement program (Expandir a busca)
ratio decrease » to decrease (Expandir a busca), rats decreases (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (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)
code ratio » node ratio (Expandir a busca), code radio (Expandir a busca), cod:n ratio (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code ratio decrease placement program ) OR ( python code python python programming ))~.
