Perhaps you should try some spelling variations:
component control » componente controle (Expand search), compliant control (Expand search), component context (Expand search)
sampling method » sampling methods (Expand search)
using sampling » using subsampling (Expand search), using saline (Expand search), using samples (Expand search)
method python » method method (Expand search), python 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 control program ) OR ( using sampling method python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder tree component control program ) OR ( using sampling method python programming ))*.
