Talvez deva tentar algumas variações de ortografia:
treated effluents » treated effluent (Expandir a busca)
effluents python » fluent python (Expandir a busca), effluents with (Expandir a busca), effluents on (Expandir a busca)
python treated » cotton treated (Expandir a busca), pythiosis treated (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)
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 ( python treated effluents python programming ))~.
