Perhaps you should try some spelling variations:
components control » componente controle (Expand search), components central (Expand search), componentes contra (Expand search)
varying coupling » varying couplings (Expand search), varying cutting (Expand search), varying modeling (Expand search)
coupling python » coupling protein (Expand search)
and components » yield components (Expand search), blood components (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons python (Expand search)
coder and » code and (Expand search), codes and (Expand search), poder and (Expand search)

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( coder AND components control program ) OR ( varying coupling python python programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( coder and components control program ) OR ( varying coupling python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder and components control program ) OR ( varying coupling python python programming ))*.
