Talvez deva tentar algumas variações de ortografia:
extraction method » extraction methods (Expandir a busca)
code extraction » model extraction (Expandir a busca), ore extraction (Expandir a busca), coffee extraction (Expandir a busca)
method decrease » method increased (Expandir a busca), method increases (Expandir a busca), method degrees (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
code code » code cdc (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code code extraction method decrease ) OR ( _ python python python programming ))~.
