com.stratio.cassandra.lucene.builder.search.condition.Condition

com.stratio.cassandra.lucene.builder.search.condition.FuzzyCondition

public class FuzzyCondition
extends Condition

A Condition that implements the fuzzy search query. The similarity measurement is based on the Damerau-Levenshtein (optimal string alignment) algorithm, though you can explicitly choose classic Levenshtein by passing false to the transpositions parameter.
