Talvez deva tentar algumas variações de ortografia:
pythons python » python python (Expandir a busca), pitons python (Expandir a busca), piton python (Expandir a busca)
decrease model » increase model (Expandir a busca), decrease sod (Expandir a busca), decrease total (Expandir a busca)
model process » modeling process (Expandir a busca), model proteins (Expandir a busca), del proceso (Expandir a busca)
decrease of » decrease in (Expandir a busca)
