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