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