Talvez deva tentar algumas variações de ortografia:
extraction method » extraction methods (Expandir a busca)
coder relations » border relations (Expandir a busca), power relations (Expandir a busca), over relations (Expandir a busca)
case extraction » cane extraction (Expandir a busca), phase extraction (Expandir a busca), based extraction (Expandir a busca)
relations case » relations cases (Expandir a busca), relations based (Expandir a busca), relations class (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
using codigo » using indigo (Expandir a busca), using coding (Expandir a busca), using codium (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder relations case extraction method ) OR ( using codigo python python programming ))~.
