• The words AND, OR and NOT may confuse the search; try adding quotes: "(( poder and components have program ) OR ( using coupling python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( poder and components have program ) OR ( using coupling python python programming ))*.
