    • Method Detail

      • setFuzziness

        public FuzzyOptions.Builder setFuzziness​(int editDistance)
        Sets the level of fuzziness used to create suggestions using a Fuzziness instance. The default value is Fuzziness.ONE which allows for an "edit distance" of one.

      • setTranspositions

        public FuzzyOptions.Builder setTranspositions​(boolean transpositions)
        Sets if transpositions (swapping one character for another) counts as one character change or two. Defaults to true, meaning it uses the fuzzier option of counting transpositions as a single change.

      • setFuzzyMinLength

        public FuzzyOptions.Builder setFuzzyMinLength​(int fuzzyMinLength)
        Sets the minimum length of input string before fuzzy suggestions are returned, defaulting to 3.

      • setFuzzyPrefixLength

        public FuzzyOptions.Builder setFuzzyPrefixLength​(int fuzzyPrefixLength)
        Sets the minimum length of the input, which is not checked for fuzzy alternatives, defaults to 1

      • setMaxDeterminizedStates

        public FuzzyOptions.Builder setMaxDeterminizedStates​(int maxDeterminizedStates)
        Sets the maximum automaton states allowed for the fuzzy expansion

      • setUnicodeAware

        public FuzzyOptions.Builder setUnicodeAware​(boolean unicodeAware)
        Set to true if all measurements (like edit distance, transpositions and lengths) are in unicode code points (actual letters) instead of bytes. Default is false.
