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