• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and computation in computer programing\") OR (\"in python python python programming\"))~".
• Removing quotes may allow a broader search: (( and computation in computer programing ) OR ( in python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computation in computer programing") OR ("in python python python programming"))*.
