Talvez deva tentar algumas variações de ortografia:
symptom decrease » system decrease (Expandir a busca), symmetry decrease (Expandir a busca)
section symptom » infection symptom (Expandir a busca), lesion symptom (Expandir a busca), infection symptoms (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
code section » code inspection (Expandir a busca), mode selection (Expandir a busca), code detection (Expandir a busca)
code code » code cdc (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code code section symptom decrease ) OR ( _ python python python programming ))~.
