Perhaps you should try some spelling variations:
component contexto » component context (Expand search), componente contextual (Expand search), componente continuo (Expand search)
contexto programa » contrato programa (Expand search), contratos programa (Expand search), contexto proposta (Expand search)
coupling python » coupling protein (Expand search)
using coupling » running coupling (Expand search), using competing (Expand search), using coupled (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons python (Expand search)
coder tree » modern tree (Expand search), under tree (Expand search), poder tres (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( coder tree component contexto programa ) OR ( using coupling python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder tree component contexto programa ) OR ( using coupling python python programming ))*.
