This pattern matches the specified target items by using a combination of literal strings and character classes. It first matches the 'PROD' or 'ORD' prefixes, followed by the respective suffixes and separators. The pattern consists of two main parts: one for the 'PROD' items and one for the 'ORD' items. For 'PROD', it matches the prefix ('PROD' or variations like 'X-PROD', 'YPROD', etc.) followed by a hyphen and then any alphanumeric characters. For 'ORD', it matches the prefix 'ORD' followed by a separator (hyphen, underscore, or dot) and then four digits, another separator (if applicable), and finally any alphanumeric characters. This ensures that all target items are matched exactly without matching any other parts of the text.
