Talvez deva tentar algumas variações de ortografia:
rating estimation » ratio estimation (Expandir a busca), rate estimation (Expandir a busca), motion estimation (Expandir a busca)
python coding » action coding (Expandir a busca), python code (Expandir a busca)
coding python » codigo python (Expandir a busca), codigos python (Expandir a busca), using python (Expandir a busca)
estimation in » estimation of (Expandir a busca)
coder python » codigo python (Expandir a busca), compra python (Expandir a busca)
coder rating » vocoder rating (Expandir a busca), power rating (Expandir a busca), code drafting (Expandir a busca)
in program » in programs (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder python coding python programming ) OR ( coder rating estimation in program ))~.
