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