Talvez deva tentar algumas variações de ortografia:
decrease preparation » decrease predation (Expandir a busca), disease preparation (Expandir a busca), release preparation (Expandir a busca)
preparation process » separation process (Expandir a busca), preparation procedures (Expandir a busca), preparation procedure (Expandir a busca)
notes decrease » not decrease (Expandir a busca), quotas decrease (Expandir a busca), not decreased (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)
code notes » corde notes (Expandir a busca), coffe notes (Expandir a busca), some notes (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code notes decrease preparation process ) OR ( python coding python python programming ))~.
