Talvez deva tentar algumas variações de ortografia:
decrease observed » case observed (Expandir a busca), decay observed (Expandir a busca)
observed programa » observer program (Expandir a busca), server programa (Expandir a busca)
lines decrease » life decrease (Expandir a busca), times decrease (Expandir a busca), leaves decrease (Expandir a busca)
piton python » pitons python (Expandir a busca), in python (Expandir a busca), with python (Expandir a busca)
python code » python coding (Expandir a busca), python redes (Expandir a busca)
code lines » code lives (Expandir a busca), code clones (Expandir a busca), code linear (Expandir a busca)
code piton » code position (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code lines decrease observed programa ) OR ( python code piton python programming ))~.
