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