Perhaps you should try some spelling variations:
competencies control » competencia controle (Expand search), competencias contra (Expand search), companies control (Expand search)
and competencies » and competences (Expand search), and competence (Expand search), of competencies (Expand search)
method python » method method (Expand search), python python (Expand search)
using cost » using cone (Expand search), using co (Expand search), using co2 (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: (( code AND competencies control program ) OR ( using cost method python programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( code and competencies control program ) OR ( using cost method python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( code and competencies control program ) OR ( using cost method python programming ))*.
