      Gets the fuzziness used when evaluated to a fuzzy query type.
    • prefixLength

      public MatchQueryBuilder prefixLength​(int prefixLength)
      Sets the length of a length of common (non-fuzzy) prefix for fuzzy match queries
      Parameters:
      prefixLength - non-negative length of prefix
