Fuzzy Matching Logic

A method of matching where algorithms are used to compare character strings and detect recurring patterns within these strings. Common algorithms are Soundex, Levenshtein Distance and Double Metaphone which find similarities based on patterns and similarities. It is called a "fuzzy match" because the match is not exact, like if you were looking at the two records out of focus, they would look the same, but would be a bit fuzzy.
