• The words AND, OR and NOT may confuse the search; try adding quotes: "(( some NOT decrease basic programming ) OR ( vpython colisoes python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( some NOT decrease basic programming ) OR ( vpython colisoes python python programming ))*.
