Talvez deva tentar algumas variações de ortografia:
java programming » and programming (Expandir a busca), based programming (Expandir a busca), goal programming (Expandir a busca)
coder detection » code detection (Expandir a busca), border detection (Expandir a busca), corner detection (Expandir a busca)
teaching lines » teaching lives (Expandir a busca), teaching links (Expandir a busca), teaching linear (Expandir a busca)
song teaching » tongue teaching (Expandir a busca), nursing teaching (Expandir a busca), singing teaching (Expandir a busca)
lines python » in python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder detection using java programming ) OR ( song teaching lines python programming ))~.
