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