Fuzzy matching can match strings that are not exactly the same but have similar characteristics and similar patterns. The duplicate check batch job, duplicate contact check batch job, and matching batch job rely on fuzzy matching to identify duplicates and matches.
Matching is a two step process that determines a match score between two records. First,
performs an exact match on the matching segments to exclude records that are unlikely to have matches. Then,
performs a fuzzy match on the remaining records to calculate a match score between pairs of records. If the match score of the two records achieves the match score threshold,
considers the two records a match.
You can configure how the fuzzy matching process calculates the match score. Use the Fuzzy Data Comparison page to compare two records to test your matching settings.
