Language Analyzers

edit

Language Analyzers

edit

A set of analyzers aimed at analyzing specific language text. The following types are supported: arabic, armenian, basque, brazilian, bulgarian, catalan, cjk, czech, danish, dutch, english, finnish, french, galician, german, greek, hindi, hungarian, indonesian, irish, italian, latvian, lithuanian, norwegian, persian, portuguese, romanian, russian, sorani, spanish, swedish, turkish, thai.

Configuring language analyzers

edit

Stopwords

edit

All analyzers support setting custom stopwords either internally in the config, or by using an external stopwords file by setting stopwords_path. Check Stop Analyzer for more details.

Excluding words from stemming

edit

The stem_exclusion parameter allows you to specify an array of lowercase words that should not be stemmed. Internally, this functionality is implemented by adding the keyword_marker token filter with the keywords set to the value of the stem_exclusion parameter.

The following analyzers support setting custom stem_exclusion list: arabic, armenian, basque, bulgarian, catalan, czech, dutch, english, finnish, french, galician, german, hindi, hungarian, indonesian, irish, italian, latvian, lithuanian, norwegian, portuguese, romanian, russian, sorani, spanish, swedish, turkish.

Reimplementing language analyzers

edit

The built-in language analyzers can be reimplemented as custom analyzers (as described below) in order to customize their behaviour.

If you do not intend to exclude words from being stemmed (the equivalent of the stem_exclusion parameter above), then you should remove the keyword_marker token filter from the custom analyzer configuration.

arabic analyzer

edit

The arabic analyzer could be reimplemented as a custom analyzer as follows:

{
  "settings": {
    "analysis": {
      "filter": {
        "arabic_stop": {
          "type":       "stop",
          "stopwords":  "_arabic_" 
        },
        "arabic_keywords": {
          "type":       "keyword_marker",
          "keywords":   [] 
        },
        "arabic_stemmer": {
          "type":       "stemmer",
          "language":   "arabic"
        }
      },
      "analyzer": {
        "arabic": {
          "tokenizer":  "standard",

            "arabic_stop",
            "arabic_normalization",
            "arabic_keywords",
            "arabic_stemmer"
          ]
        }
      }
    }
  }
}

This filter should be removed unless there are words which should be excluded from stemming.

This filter should be removed unless there are words which should be excluded from stemming.

  "settings": {
    "analysis": {
      "filter": {
        "turkish_stop": {
          "type":       "stop",
          "stopwords":  "_turkish_" 
        },

          "type":       "keyword_marker",
          "keywords":   [] 
        },
        "turkish_stemmer": {
