This includes advanced emails with plus signs and hyphens, dates with different separators and potential invalid candidates, along with phone numbers in various formats including international codes and parenthesized area codes. The target items are interleaved with other text to introduce potential false positives. This challenge forces the regex to use advanced techniques like negative lookahead/lookbehind, grouping, alternations, and precise capturing to filter out similar but invalid patterns.", "timestamp": 1742323935509}]
