Fuzzy Matching on First Name

When thinking about fuzzy matching for the First Name attribute, there are at least two tactics that can be employed which you should consider. First, if your objective is to successfully find and match cases of first names or last names that have misspellings, you could use the DamerauLevenshteinDistance or the DynamicDamerauLevenshteinDistance comparator, coupled with the FuzzyTextAndNumberMatchToken. Another tactic would be to use the DoubleMetaphoneComparator and DoubleMetaphoneMatchToken which uses a phonetic approach AND takes common misspellings into account automatically. Lastly if you wish to employ either of the previous suggestions but also match across common synonyms, then you can add the use of the Name Dictionary Cleanser to your rule.

Full Name

This is a good tactic if you want to avoid matching on first and last names independently. You can use the profile-level cleanser to form the Full Name as a concatenation of the First and Last names if the full name is not available to you directly.

Since the combined name will naturally increase the statistical amount of variation into the match process, you should use the Fuzzy comparison operator and choose fuzzy comparator and token classes as you see fit.

Using Reference Attributes in a Match Rule

We should avoid the use of reference attributes in match rules as much as possible. Significant use of reference attributes in match rules increase performance overhead for the platform. Whenever possible, denormalization of attributes within an entity is better for performance.
