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