Talvez deva tentar algumas variações de ortografia:
by preprocessing » the preprocessing (Expandir a busca), and preprocessing (Expandir a busca), via preprocessing (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)
deciding by » deciding on (Expandir a busca), deciding _ (Expandir a busca), decisions by (Expandir a busca)
in python » _ python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coder deciding by preprocessing ) OR ( in python python python programming ))~.
