Talvez deva tentar algumas variações de ortografia:
coding efficiency » feeding efficiency (Expandir a busca), cutting efficiency (Expandir a busca), spending efficiency (Expandir a busca)
robot programming » robots programming (Expandir a busca), goal programming (Expandir a busca), cone programming (Expandir a busca)
efficiency robot » efficiency root (Expandir a busca), efficient robot (Expandir a busca), efficiency but (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coder coding » modern coding (Expandir a busca), color coding (Expandir a busca), odor coding (Expandir a busca)
in python » _ python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coding efficiency robot programming ) OR ( in python python python programming ))~.
