This pattern is designed to precisely match each item from the provided target list while ensuring no other text items are matched. It combines multiple groups using alternations (|) to handle different item categories such as email addresses, phone numbers, dates, and IDs. Specific and careful conditions are set within each group to meet the unique characteristics of valid targets while excluding similar invalid ones. It relies on patterns like strict domain matching for emails, delimiters and formats for phone numbers and dates, while making use of word boundaries to ensure accurate and isolated matches.
