Perhaps you should try some spelling variations:
components contract » componentes contra (Expand search), components central (Expand search), components constraints (Expand search)
contract program » contrato programa (Expand search), control program (Expand search), control programs (Expand search)
line components » the components (Expand search), core components (Expand search), tree components (Expand search)
coupling python » coupling protein (Expand search)
using coupling » running coupling (Expand search), using competing (Expand search), using coupled (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 line components contract program ) OR ( using coupling python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder line components contract program ) OR ( using coupling python python programming ))*.
