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