The pattern is built using alternation to match four distinct groups:

1. Email addresses: Matches the three specific email formats with exact characters including dots, exclamation marks, and underscores.
2. Transaction IDs: Matches the specific TRX patterns with their exact formats including @, -, /, and _ characters.
3. Dates: Matches the three specific date formats including the "1st" ordinal.
4. IP addresses: Matches the two specific IP addresses.

Each part is carefully constructed to match only the target items and avoid matching similar but invalid items in the text. The pattern uses exact character sequences where possible and appropriate character classes where needed.
