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