The pattern is built using alternation to match exactly the required strings:
1. Email part: Uses 3 specific email patterns joined by |
2. Phone part: Matches the two specific phone number formats
3. Date part: Matches the three date formats with their specific separators
4. ID part: Matches the two specific ID formats
The pattern uses \. to escape dots, \( \) to escape parentheses, and + to escape the plus sign in the phone number.
Each section is carefully constructed to match only the exact strings provided and nothing else.
