This example provides information about how to use a custom comparator.

Please review the example match rule configuration below. It has the following characteristics:

• Uses a custom comparator class and custom match token class for the Organization Name.
• Uses the DistinctWords comparator and DistinctWords match token class as the basis for the custom classes.
• Notice the symmetry of how the comparator and match token classes are defined.
• Uses the Stemmer and Soundex functions within the custom classes.
• Uses a custom noise words dictionary.
• Uses exact match on five attributes, and fuzzy on one attribute.
• Only operates on profiles where the address type = Shipping
• Only operates on profiles where the OrgJourneyStatus is not Generic Account or House Account.
• Uses ignoreInToken to suppress tokenization on four attributes as they are deemed not helpful for identifying match candidates
• Unnecessarily uses ExactOrNull and ExactOrAllNull together. Only one of them should have been used.
