Tolerances
Some built-in data identifiers have three versions, each with a different tolerance level associated with it. Tolerance levels determine how many instances of an identifier must appear within a document for that document to be considered a match. There are three tolerance levels:
- Lenient tolerance requires only a single instance of an identifier to appear within a document for that document to be considered a match.
- Moderate tolerance requires more occurrences of an identifier than Lenient tolerance, but fewer than Strict tolerance. (The exact number varies depending upon the identifier.)
- Strict tolerance requires the most occurrences of an identifier to appear within a document for that document to be considered a match. (The exact number varies depending upon the identifier.)
For identifiers that support tolerance levels, you can choose the tolerance level that best matches your level of concern for catching every occurrence of those identifiers.
