Talvez deva tentar algumas variações de ortografia:
case conversion » cash conversion (Expandir a busca), phase conversion (Expandir a busca), based conversion (Expandir a busca)
decrease their » decrease the (Expandir a busca), increase their (Expandir a busca), decreases the (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
code python » codigo python (Expandir a busca), pacote python (Expandir a busca)
their case » their care (Expandir a busca), their classes (Expandir a busca), their course (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease their case conversion process ) OR ( python code python python programming ))~.
