• Performing a fuzzy search may retrieve terms with similar spellings: (("applying computation using linear programming") OR ("using code from python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"applying computation using linear programming\") OR (\"using code from python programming\"))".
• Removing quotes may allow a broader search: (( applying computation using linear programming ) OR ( using code from python programming )).
• Adding a wildcard symbol may retrieve word variants: (("applying computation using linear programming") OR ("using code from python programming"))*.
