Talvez deva tentar algumas variações de ortografia:
c recognition » act recognition (Expandir a busca), and recognition (Expandir a busca), ion recognition (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
code coding » code cloning (Expandir a busca), code codigo (Expandir a busca), code according (Expandir a busca)
code code » code cdc (Expandir a busca)
coding c » coding co (Expandir a busca), coding _ (Expandir a busca), coding h (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code code coding c recognition ) OR ( _ python python python programming ))~.
