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