Talvez deva tentar algumas variações de ortografia:
frictional interface » frictional interfaces (Expandir a busca), functional interfaces (Expandir a busca), funcional interface (Expandir a busca)
with frictional » with fractional (Expandir a busca), with functional (Expandir a busca), with friction (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)
coder with » codes with (Expandir a busca), code with (Expandir a busca), cover with (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 with frictional interface ) OR ( in python python python programming ))~.
