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