• The words AND, OR and NOT may confuse the search; try adding quotes: "(( proper motion in methodology problems ) OR ( using on python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( proper motion in methodology problems ) OR ( using on python python programming ))*.
