Talvez deva tentar algumas variações de ortografia:
vpython collisions » vpython colisoes (Expandir a busca), proton collisions (Expandir a busca), photon collisions (Expandir a busca)
collisions python » collisions within (Expandir a busca), collisions with (Expandir a busca), collisions on (Expandir a busca)
code decrease » oxide decrease (Expandir a busca), roads decrease (Expandir a busca), to decrease (Expandir a busca)
decrease fear » decrease after (Expandir a busca), decrease their (Expandir a busca), decrease cell (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
fear program » year program (Expandir a busca), year programm (Expandir a busca), seer program (Expandir a busca)
code code » code cdc (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code code decrease fear program ) OR ( vpython collisions python python programming ))~.
