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 problem » complex problems (Expandir a busca)
and decrease » and decreases (Expandir a busca), and decreased (Expandir a busca), and increase (Expandir a busca)
python code » python coding (Expandir a busca), python redes (Expandir a busca)
pitons » citons (Expandir a busca), pitoni (Expandir a busca), pitoes (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code and decrease complex problem ) OR ( python code pitons python programming ))~.
