Talvez deva tentar algumas variações de ortografia:
decrease their » decrease the (Expandir a busca), increase their (Expandir a busca), decreases the (Expandir a busca)
their disease » the disease (Expandir a busca), hair diseases (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)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
pvc programa » pac programa (Expandir a busca), pic programa (Expandir a busca), p1mc programa (Expandir a busca)
disease pvc » disease pd (Expandir a busca), disease pad (Expandir a busca), disease pdq (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease their disease pvc programa ) OR ( python coding python python programming ))~.
