public final class AnalyzerNames extends Object
Constants for the names of built-in analyzers.

  • Field Details

    • DEFAULT

      public static final String DEFAULT
      The default analyzer.

      This analyzer will generally be used for full-text field that don't require specific analysis.

      Unless overridden by explicit analysis configuration, the default analyzer will be the standard analyzer:

      • First, tokenize using the standard tokenizer, which follows Word Break rules from the Unicode Text Segmentation algorithm, as specified in Unicode Standard Annex #29.
      • Then, lowercase each token.
      See Also:

    • STANDARD

      public static final String STANDARD
      The standard analyzer.

      Unless overridden by explicit analysis configuration, this analyzer behaves as follows:

      • First, tokenize using the standard tokenizer, which follows Word Break rules from the Unicode Text Segmentation algorithm, as specified in Unicode Standard Annex #29.
      • Then, lowercase each token.
      See Also:

    • SIMPLE

      public static final String SIMPLE
      The simple analyzer.

      Unless overridden by explicit analysis configuration, this analyzer behaves as follows:

      • First, tokenize by assuming non-letter characters are separators.
      • Then, lowercase each token.
      See Also:

    • WHITESPACE

      public static final String WHITESPACE
      The whitespace analyzer.

      Unless overridden by explicit analysis configuration, this analyzer behaves as follows:

      • First, tokenize by assuming whitespace characters are separators.
      • Do not change the tokens.
      See Also:

    • STOP

      public static final String STOP
      The stop analyzer.

      Unless overridden by explicit analysis configuration, this analyzer behaves as follows:

      • First, tokenize by assuming non-letter characters are separators.
      • Then, lowercase each token.
      • finally, remove english stop words.
      See Also:

    • KEYWORD

      public static final String KEYWORD
      The keyword analyzer.

      Unless overridden by explicit analysis configuration, this analyzer does not change the text in any way.

      With this analyzer, a full text field would behave similarly to a keyword field, but with fewer features: no terms aggregations, for example.

      Consider using a keyword field instead.
