Pattern Matching Expressions—also known as Regular Expressions—are compared to text and token data in the Pattern Matching process as well as several other Quick Fields processes and features. When the text or token information matches the pattern, Quick Fields can perform some action, such as identifying the document as belonging to a document class, automatically annotating the text that meets the pattern, or substituting different text. Pattern Matching Expressions can also be used as constraints on particular fields or tokens to ensure data used in them meets specified criteria.
