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