Talvez deva tentar algumas variações de ortografia:
relation author » relation actor (Expandir a busca), relative author (Expandir a busca), relation action (Expandir a busca)
child relation » child relations (Expandir a busca), child relationship (Expandir a busca)
python coding » action coding (Expandir a busca), python code (Expandir a busca)
coding python » codigo python (Expandir a busca), codigos python (Expandir a busca), using python (Expandir a busca)
author python » altair python (Expandir a busca), author person (Expandir a busca), python python (Expandir a busca)
coder python » codigo python (Expandir a busca), compra python (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coder python coding python ) OR ( child relation author python programming ))~.
