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