Talvez deva tentar algumas variações de ortografia:
class processes » last processes (Expandir a busca), loss processes (Expandir a busca), plasma processes (Expandir a busca)
decrease spot » decrease sod (Expandir a busca), decrease soon (Expandir a busca), decrease of (Expandir a busca)
disease class » disease case (Expandir a busca), disease cross (Expandir a busca), disease cases (Expandir a busca)
spot disease » host disease (Expandir a busca), wilt disease (Expandir a busca)
python api » python and (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: (( decrease spot disease class processes ) OR ( python api pitons python programming ))~.
