Talvez deva tentar algumas variações de ortografia:
symptom decrease » system decrease (Expandir a busca), symmetry decrease (Expandir a busca)
decrease study » decrease std (Expandir a busca), increase study (Expandir a busca), decreased steady (Expandir a busca)
study program » study programs (Expandir a busca), study programme (Expandir a busca), student program (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
node symptom » not symptom (Expandir a busca), sole symptom (Expandir a busca), voice symptom (Expandir a busca)
python code » python coding (Expandir a busca), python redes (Expandir a busca)
code python » codigo python (Expandir a busca), pacote python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( node symptom decrease study program ) OR ( python code python python programming ))~.
