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