Talvez deva tentar algumas variações de ortografia:
coder contribution » model contribution (Expandir a busca), code contributions (Expandir a busca), codon contribution (Expandir a busca)
contribution model » distribution model (Expandir a busca), attribution model (Expandir a busca), contribution des (Expandir a busca)
coding program » cloning program (Expandir a busca), loading program (Expandir a busca), cooling programs (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
model coding » modern coding (Expandir a busca), model cooling (Expandir a busca), novel coding (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• As palavras AND, OR e NOT pode ocasionar problemas na busca; tente utilizar as aspas: "(( coder contribution model coding program ) OR ( on python python python programming ))~".
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: (( coder contribution model coding program ) OR ( on python python python programming ))*.
