Talvez deva tentar algumas variações de ortografia:
disease problem » disease profles (Expandir a busca), disease profiles (Expandir a busca), distance problem (Expandir a busca)
problem process » problema processo (Expandir a busca), problemas processo (Expandir a busca), problems progress (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
decrease and » decreases and (Expandir a busca), decrease in (Expandir a busca), decrease of (Expandir a busca)
python dados » python data (Expandir a busca), python redes (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease and disease problem process ) OR ( python dados python python programming ))~.
