Talvez deva tentar algumas variações de ortografia:
functional quality » functional ability (Expandir a busca), national quality (Expandir a busca), nutritional quality (Expandir a busca)
quality decrease » quality decreases (Expandir a busca), quality increase (Expandir a busca), quality increases (Expandir a busca)
code functional » core functional (Expandir a busca), some functional (Expandir a busca), care functional (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 quality decrease ) OR ( _ python python python programming ))~.
