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