Match Keys Used with Matching Rules
- The matching rule equation that determines the arrangement of the fields is rewritten into a standardized format that translates the OR statements into AND statements.
- Values for fields in the matching rule are normalized.
- A match key is created using the field combinations specified in the standardized field format. Matching rules can have multiple match keys. For standard matching rules or custom rules with standard field combinations, predefined match keys are used.
- The match key is used to combine normalized field values for each record.
