My regex pattern works by using alternation (|) to match any one of the target items. Since we need to match exactly these items and nothing else, I'm creating a pattern that matches each item literally:

1. For emails: "support@example\\.com|support@company\\.org" - I escape the dots to match them literally
2. For phone: "\\+1-800-555-0199" - I escape the plus sign since it's a special character in regex
3. For dates: "2023-10-25|10/26/2023|10\\.27\\.2023" - I escape the dots in the third date format
4. For IDs: "ID-1234|CODE-5678|ABCD-9012XYZ|ABC-001-XYZ|DEF-0023-XYZ"

By using alternation with the exact strings, the pattern will only match the specified targets and nothing else. Alternation works by attempting to match each alternative in turn until one succeeds.
