Enum Constant Detail

INTERNAL

public static final TermSuggestionBuilder.StringDistanceImpl INTERNAL

This is the default and is based on damerau_levenshtein, but highly optimized for comparing string distance for terms inside the index.

DAMERAU_LEVENSHTEIN

public static final TermSuggestionBuilder.StringDistanceImpl DAMERAU_LEVENSHTEIN

String distance algorithm based on Damerau-Levenshtein algorithm.

LEVENSTEIN

public static final TermSuggestionBuilder.StringDistanceImpl LEVENSTEIN

String distance algorithm based on Levenstein edit distance algorithm.

JAROWINKLER

public static final TermSuggestionBuilder.StringDistanceImpl JAROWINKLER

String distance algorithm based on Jaro-Winkler algorithm.

NGRAM

public static final TermSuggestionBuilder.StringDistanceImpl NGRAM

String distance algorithm based on character n-grams.

Method Detail

values

public static TermSuggestionBuilder.StringDistanceImpl[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (TermSuggestionBuilder.StringDistanceImpl c : TermSuggestionBuilder.StringDistanceImpl.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TermSuggestionBuilder.StringDistanceImpl valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

writeTo

public void writeTo(StreamOutput out)
             throws java.io.IOException

Description copied from interface: Writeable

Write this into the StreamOutput.

Specified by:

writeTo in interface Writeable

Throws:

java.io.IOException

readFromStream

public static TermSuggestionBuilder.StringDistanceImpl readFromStream(StreamInput in)
                                                               throws java.io.IOException

Throws:

java.io.IOException

resolve

public static TermSuggestionBuilder.StringDistanceImpl resolve(java.lang.String str)

toLucene

public abstract org.apache.lucene.search.spell.StringDistance toLucene()
