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