Talvez deva tentar algumas variações de ortografia:
based processes » based process (Expandir a busca), and processes (Expandir a busca)
disease based » disease caused (Expandir a busca), disease case (Expandir a busca), diseases caused (Expandir a busca)
decrease old » decrease food (Expandir a busca), decrease of (Expandir a busca), decrease and (Expandir a busca)
python reais » python regius (Expandir a busca), python redes (Expandir a busca)
reais pitons » reais pontos (Expandir a busca), reais python (Expandir a busca), reais pos (Expandir a busca)
old disease » and disease (Expandir a busca), cord diseases (Expandir a busca), and diseases (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease old disease based processes ) OR ( python reais pitons python programming ))~.
