Talvez deva tentar algumas variações de ortografia:
decrease complex » disease complex (Expandir a busca), decreased compared (Expandir a busca), protease complex (Expandir a busca)
complex problems » complex projects (Expandir a busca)
python based » action based (Expandir a busca)
based pitons » based peptones (Expandir a busca), based epitope (Expandir a busca), based tectons (Expandir a busca)
in decrease » in decreased (Expandir a busca), on decrease (Expandir a busca), pain decrease (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease in decrease complex problems ) OR ( python based pitons python programming ))~.
