Talvez deva tentar algumas variações de ortografia:
code functional » core functional (Expandir a busca), some functional (Expandir a busca), care functional (Expandir a busca)
functional rate » functional date (Expandir a busca), functional state (Expandir a busca), functional ratio (Expandir a busca)
rate decrease » rats decreases (Expandir a busca), ratio decrease (Expandir a busca), rate increase (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 functional rate decrease ) OR ( _ python python python programming ))~.
