public class FuzzyTerm
extends IntervalFunction

An interval function equivalent to FuzzyQuery. A fuzzy term expands to a disjunction of intervals of terms that are within the specified maxEdits from the provided term. A limit of maxExpansions prevents the internal implementation from blowing up on too many potential candidate terms.
