Talvez deva tentar algumas variações de ortografia:
author programming » python programming (Expandir a busca), method programming (Expandir a busca), motor programming (Expandir a busca)
java programming » and programming (Expandir a busca), based programming (Expandir a busca), goal programming (Expandir a busca)
complex relation » complex reaction (Expandir a busca), complex reflection (Expandir a busca), complexa relato (Expandir a busca)
relation author » relation actor (Expandir a busca), relative author (Expandir a busca), relation action (Expandir a busca)
python complex » python computer (Expandir a busca), prison complex (Expandir a busca)

coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)
python java » python data (Expandir a busca), python capaz (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coder python java programming ) OR ( python complex relation author programming ))~.
