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