Talvez deva tentar algumas variações de ortografia:
cronica programa » crianca programa (Expandir a busca), pronera programa (Expandir a busca), pratica programa (Expandir a busca)
causing cronica » causing chronic (Expandir a busca), causing clinical (Expandir a busca), causing colonic (Expandir a busca)
python causing » pathogen causing (Expandir a busca), python coding (Expandir a busca), pathogens causing (Expandir a busca)
coating python » coating method (Expandir a busca), coating pathogens (Expandir a busca)
using coating » using coatings (Expandir a busca), using rotating (Expandir a busca), using cutting (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder python causing cronica programa ) OR ( using coating python python programming ))~.
